So i have a problem and it's about inequality, and it required me to answer it in a complete sentence, little help please :)
Problem: Glenda has a $40 gift certificate to a cafe that sells her favorite tuna sandwich for $3.75 after tax. What are the possible number of tuna sandwiches that Glenda can buy with her gift certificate?! And it even said to define a variable, write an inequality then solve. Anyone help me? Thanks :)

ok think of the equal sign as line, and you want to balance each side out

if you have 3 times some number = 15 then 3 times what would give you 15?

kk keep it going :)

x is just a number that we don't know what it is yet but we knw that 3*(this number) is 15
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
now if we didn't know that 3*5 is 15 we could take the 3 to the other side and then all we have on the 1 side is x=
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
that would be right it it were 3+x=15 but if it's 3*x we have to divide 3

think of the equal sign like the opposite side, so if you 3*5=15 then 3=15/5

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
if it's multiplied on 1 side then to move it you devide the other side by what your moving, if it's just + or  then you change the sign and add or subtract from the other side

so 3x=15 then its gonna be 15+3=x?

can you put it in a simple way ?
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
no if x is next to a number without a + or minus between that means x multiplied by the number

ok gotcha i know that but how to make it balance on either sides?
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
just like x/3 is x divided by 3
 2 years ago

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
so x=15?
 2 years ago

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
because 15/3=3
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
so if you had \[\frac{ x }{ 3 }=5\] that would mean that you would need to multiply both sides by 3 so you would get \[\frac{ 3x }{ 3 }=5*3\] the 3 and 3 cancle out and your left with x=3*5 or 15

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
yes i think your starting to understand a bit
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
they are still equal if you do the same thing to both sides so to move 3+x=15 we would subtract 3 from both sides and we get x+12 if we have 3x=15 we have to divide both sides by 3 so we get x=15/3 or 5 if we have x/3= 5 we multiply both sides by 3 and get x= 3*5 or 15

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
OH i get it so back to the problem 3x=15 would be x=5?

yes that is correct lets' try this one to be sure you understand \[4x=20\] what is x?

So what about this prbolem? : 2/3 > 1/2  d/6 / < mean " over". Like 2 over 3, 1 over 2 and d over 6

you are trying to get d by itself

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
kick the d out?
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
no we want to save that for last wet's get the addition/subtraction out of the way first, \[\frac{ 2 }{3 }>\frac{ 1 }{ 2 }\frac{ d }{ 6 }\] so if we move 1/2 over it becomes 1/2
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
so\[\frac{ 2 }{ 3 }\frac{ 1 }{ 2 }>\frac{ d }{ 6 }\] now how do we subtract fractions?

uhmm divide it?

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
don't worry about the d/6 right now one piece at a time, math is all in baby steps, when we try to skip stuff we make mistakes so think of it as doing what we know how to make it simpler and right now we can make it simple by subtracting our fractions 2/31/2

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
yeah some day you can help out a seventh grader lol and it's all be good

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
haha thanks :) OK back to the prob. so 2/3  1/2 gonna be 1?
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
so to subtract the denominator has to be the same so we make them the same by finding something in common or cross multiplying so \[\frac{ 2*2 }{ 3*2 }  \frac{ 1*3 }{ 2*3 } = \frac{ 4 }{ 6 }\frac{ 3 }{6 }\]
 2 years ago

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
oh yeah i forgot im not that good at math :P or sp its gonna be 1/6 ?
 2 years ago

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
now we have \[\frac{ 1 }{ 6 }>\frac{ d }{6 }\] what would happen if we multiplied both sides by 6?
 2 years ago

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
uhm it still gonna be the same number. But since it lready 6 so i dont think we have to

multiply it right?

Jusaquikie Group TitleBest ResponseYou've already chosen the best response.0
yes so what is 6/6

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
oh so the answer gonna 6?

no, if you have a slice of pizza that is 1/6 of the pizza and then you multiply that by 6 what do you have?

the bottom number means that your top number is cut in to that many pieces so 1/6 of a pizza means that you have 6 pieces to make a whole pizza

Jameshappy Group TitleBest ResponseYou've already chosen the best response.0
so the answer is 6/6?
