Best ResponseYou've already chosen the best response.2Someone please explain how I would start doing this

Nnesha

Best ResponseYou've already chosen the best response.5start with distributive property \[\huge\rm \color{Red}{a}(b+c)\] distribute the parentheses by outside number \[\large\rm \color{Red}{a} \times b + \color{Red}{a} \times c = \color{Red}{a}b+\color{Red}{a}c\]

Best ResponseYou've already chosen the best response.2@Nnesha In step B of 17, I know they just multiplied the parentheses, would I just say that?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2@Nnesha Also for 17 A I put "distribute the parentheses with the distributive property", would that be correct?

Nnesha

Best ResponseYou've already chosen the best response.5dw:1440277087992:dw look at the last one distributive property that's what they used for first question (a) \[\large\rm \frac{ 1 }{ 2 }(1+2t)=\frac{ 1 }{ 2} \times 1 + \frac{ 1 }{ 2 } \times (2t)\]

Nnesha

Best ResponseYou've already chosen the best response.5for 17 a just write *distributive property dw:1440277416871:dw

Best ResponseYou've already chosen the best response.2@Nnesha What about 17B

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.5that's same as first step they just rearrange 2nd term \[\frac{ 1 }{ 2 } \times 2t = (\frac{ 1 }{ 2 } \times 2)t\] which *associate property*

ijarritos

Best ResponseYou've already chosen the best response.2Ok so for C, would the problem in question be 1/2 x 1 + (1/2 x 2)t = 1/2 x 1 + 1 x t

ijarritos

Best ResponseYou've already chosen the best response.2And I would look at it like that in comparison to the other sheet?

Best ResponseYou've already chosen the best response.5nah you will not!! think about good stuff algebra is not just abt these properties :=)

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.5simplify means make something easier to understand u know i HATE fraction pretty sure you don't like it either so that's why i cancel out 2's to make it simple \[\frac{ 1 }{ 2 } \times 2t = (\frac{ 1 }{\cancel{ 2} } \times \cancel{2})t\]

phi
 one year ago
Best ResponseYou've already chosen the best response.5this last one is called "inverse property of multiplication"

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2is cancelling out 2's the associative property?

phi
 one year ago
Best ResponseYou've already chosen the best response.5notice \[ \frac{ 1 }{\cancel{ 2} } \times \cancel{2} \] matches your "cheat sheet" \[ \frac{ 1 }{\cancel{ a} } \times \cancel{a} =1\]

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2omg how do you even get that out of it

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2all i know about simplification is to combine like terms

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2and i dont even see that going on like what ????

phi
 one year ago
Best ResponseYou've already chosen the best response.5do you see the line that says Inverse property of multiplication?

phi
 one year ago
Best ResponseYou've already chosen the best response.5it is saying (in short hand) that if you have two numbers and one is the "flip" of the other when you multiply them you get 1 here are examples \[ 2 \cdot \frac{1}{2} \\ 3 \cdot \frac{1}{3} \\ \frac{2}{3}\cdot \frac{3}{2}\]

Best ResponseYou've already chosen the best response.2the teacher said this was "review work" and I don't even know how do do this

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2like before she starts teaching us things and I don't even know the basics

phi
 one year ago
Best ResponseYou've already chosen the best response.5in that case, you are learning properties that are useful if you want to do algebra. Do you understand the multiply by the inverse idea? does it make sense 2*1/2 = 1

ijarritos

Best ResponseYou've already chosen the best response.2Are they using PEMDAS in 17a to get to 17b?

phi
 one year ago
Best ResponseYou've already chosen the best response.5what is the multiplicative inverse of 4/5 ? (what do you multiply it by so you get 1)?

phi
 one year ago
Best ResponseYou've already chosen the best response.5we'll get to 17a in just a minute.

phi
 one year ago
Best ResponseYou've already chosen the best response.5Do you have time to learn this now?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2And I don't know what I'd multiply by 4/5

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. that is the property you want to memorize notice when you multiply fractions you multiply top times top and bottom times bottom \[ \frac{4}{5}\cdot \frac{5}{4} = \frac{20}{20} =1 \] though it is better to notice that you have 5 up top and 5 down below and they "divide out" to 1 ditto for the 4's

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2but where did you get the 5/4 from

phi
 one year ago
Best ResponseYou've already chosen the best response.5if you start with 4/5 (think of this as "a" ) then your cheat sheet says, multiply by 1/a \[ \frac{1}{\frac{4}{5}} \] and there is a way to simplify that so it looks like \(\frac{5}{4} \)

phi
 one year ago
Best ResponseYou've already chosen the best response.5but it is easier (for me) to remember, "flip it" if you have a whole number like 2, then write it as 2/1, and now flip it to get 1/2

phi
 one year ago
Best ResponseYou've already chosen the best response.5that is enough about the multiplicative inverse. how far did you get answering your questions?

Best ResponseYou've already chosen the best response.5what is the difference between line 17a and 17b?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.21/2 was multiplied into 2 and t so distributive property

phi
 one year ago
Best ResponseYou've already chosen the best response.5no , I mean the exactly what symbols are different? most of the line is identical but there is a difference in what is written down.

phi
 one year ago
Best ResponseYou've already chosen the best response.5the difference is this part \[ \frac{1}{2}(2t) \text{ vs } \left( \frac{1}{2}\cdot 2 \right) t \]

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2Right I knew that but just didn't know how to explain it

phi
 one year ago
Best ResponseYou've already chosen the best response.5in case it is not obvious both mean 1/2 times 2 times t the only difference is where the parens are. (in theory that could make a difference, because PEDMAS says you do the stuff in parens first) but when you multiply a bunch of numbers (or letters), you are allowed to change where you put the parens.

phi
 one year ago
Best ResponseYou've already chosen the best response.5do you see the property on your cheat sheet that shows "moving the parens" when multiplying?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2Associative property

phi

Best ResponseYou've already chosen the best response.5yes, specifically associative property of multiplication

ijarritos

Best ResponseYou've already chosen the best response.2inverse property of multiplication?

phi
 one year ago
Best ResponseYou've already chosen the best response.5before moving on, let's make sure this make sense if you had 2*3*4*5*6 does it matter if we do 2*3 first or 5*6 ?

phi
 one year ago
Best ResponseYou've already chosen the best response.5ok, so I hope that makes sense. if you have 2*3*4*5 you can associate them into pairs any way you like. for b to c, yes, that is the inverse property of multiplication

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.21/2 x 1 is 1 and 1 x t is 1

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2i meant 1 x 1/2 is 1/2

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes, and that is an important property

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2I know how it works im just trying to find which property

phi
 one year ago
Best ResponseYou've already chosen the best response.5look for 1 times "something" equals "something"

ijarritos

Best ResponseYou've already chosen the best response.5what is the exact difference between the left and right sides of 18a?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2are there alot of trolls like that? xD

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes, specifically when adding

phi
 one year ago
Best ResponseYou've already chosen the best response.5so look for a property related to addition that shows "switching"

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2Is it associative property of addition?

phi
 one year ago
Best ResponseYou've already chosen the best response.5associative is "where to put the parens"

phi
 one year ago
Best ResponseYou've already chosen the best response.5we have (2+a) vs (a+2) parens did not change what changed was 2+a became a+2 look for that rule on your list

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2commutative property of addition?

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. they show a+b= b+a and that shows the "switching around" that you noticed with 2+a and a+2

phi
 one year ago
Best ResponseYou've already chosen the best response.5now for 18a to 18b what is different?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2Brackets are switched around

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2distributive property?

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. we sometimes use brackets instead of parens if it makes the expression easier to read. what rule comes to mind when you change where you put parens?

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. associate property of addition they start with (a+2) + (2) you can "move the parens" which is allowed by the associative property a+ (2 + (2))

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2are c and d identity property of addition?

phi
 one year ago
Best ResponseYou've already chosen the best response.5what is the difference between line 18b and 18c ?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2the addition in the brackets is added

phi
 one year ago
Best ResponseYou've already chosen the best response.5be more "literal" (2 + (2)) turns into 0 do you see a property that shows that?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2is 18c inverse of addition?

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. this is an important property if you have x, and you want to add something to it to make zero what do you add? you add x x + x is 0 this always works no matter what "x" is !

phi
 one year ago
Best ResponseYou've already chosen the best response.5now 18c to 18d a+0 becomes a

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2so would d be identity property of addition since its literally a+0

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2same as the cheat sheet

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. adding 0 to anything does not change it.

phi
 one year ago
Best ResponseYou've already chosen the best response.5Q19 looks almost the same as Q18

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.219a associative property of multiplication?

phi
 one year ago
Best ResponseYou've already chosen the best response.519a, what is different (the symbols) between the left side and the right side?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.25 and n are switched

phi
 one year ago
Best ResponseYou've already chosen the best response.5and be able to switch order is what property?

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes, commute means switch so here, commutative property of addition (same as in Q18a)

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2then i have no idea for 19b

phi
 one year ago
Best ResponseYou've already chosen the best response.5now 19a to 19b we "move around" parens. what property is "move parens"?

phi
 one year ago
Best ResponseYou've already chosen the best response.5I think of associative as allowing us to add or move parens (5+n) + (n) drop the parens 5+n + (n) put in new parens 5+ (n+(n))

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2inverse of addition?

phi
 one year ago
Best ResponseYou've already chosen the best response.5notice the pattern is (a+b)+c becomes a+(b+c)

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2associative property of addition?

phi
 one year ago
Best ResponseYou've already chosen the best response.519 b is associative prop of add 19 c is ?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2omg i was looking at the wrong one

phi
 one year ago
Best ResponseYou've already chosen the best response.5what is different between 19b and 19c ?

phi
 one year ago
Best ResponseYou've already chosen the best response.5(n + (n) ) becomes 0 what property is that ?

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. 19C is inverse of addition now what is different between 19C and 19D ?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2identity property of addition

phi
 one year ago
Best ResponseYou've already chosen the best response.5now the difference between 19D and 19E ?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2then 19e is inverse of miltiplication

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. Is this making sense?

phi
 one year ago
Best ResponseYou've already chosen the best response.5what is different between 21B and 21C ?

ijarritos

Best ResponseYou've already chosen the best response.2then identify again?

phi
 one year ago
Best ResponseYou've already chosen the best response.5write down the "before" and "after"

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2so for 21b i would put before identity of multiplication?

phi

phi
 one year ago
Best ResponseYou've already chosen the best response.5which property shows something on the outside of the parens "going inside" (or in this case vice versa)

phi
 one year ago
Best ResponseYou've already chosen the best response.5the change is (1*k + 1*k) becomes (1+1)*k if we write it backwards (1+1)*k becomes (1*k + 1*k) does that look familiar?

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2identity of multiplication?

phi
 one year ago
Best ResponseYou've already chosen the best response.5yes. we are going from (1*k+1*k) to (1+1)*k which is like (ab+ac) to (b+c)*a

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2im confused about c.5 to d

phi
 one year ago
Best ResponseYou've already chosen the best response.5they are saying 1+1 is replaced with a 2 now from 2k+2 to 2k + 2*1 we change 2 to 2*1 that is the identity prop of mult.

ijarritos
 one year ago
Best ResponseYou've already chosen the best response.2For 21c how does 2*1 go to 2(k+1)

phi
 one year ago
Best ResponseYou've already chosen the best response.521c is (1+1)k+2 that changes to 2k+2 by substitution of 1+1 with 2 then we change that to 2k+2*1 by ident. prop of mult.

phi
 one year ago
Best ResponseYou've already chosen the best response.5finally 2*k +2*1 becomes 2(k+1) that is the distributive property (backwards)

phi
 one year ago
Best ResponseYou've already chosen the best response.5you should try to drill into your head the pattern A*(B+C) = A*B + A*C and vice versa: AB +AC = A(B+C)

Best ResponseYou've already chosen the best response.2is 22c associative property of multiplication?

phi
 one year ago
Best ResponseYou've already chosen the best response.5(y+1) + (1) becomes y+ (1 + (1)) we are moving parens, so associative, but we are adding not multiplying

ijarritos

Best ResponseYou've already chosen the best response.2The parentheses are moved in 22d

phi
 one year ago
Best ResponseYou've already chosen the best response.522c is associative property of addition 22c to 22d the change is (1 + (1) ) becomes 0

ijarritos

Best ResponseYou've already chosen the best response.2thank you so much for helping me learn this!!

phi
 one year ago
Best ResponseYou've already chosen the best response.5OK, I hope it makes some sense. the names of the properties are not very interesting (but they will expect you to remember them), but the properties are important to know.
