S1) S S2) G S3) O S4) L S5) C those are the steps to isolate and find the value of x.
anonymous
  • anonymous
so those are the stetments right?
anonymous
  • anonymous
Yes As for the reasons 2 to 5, it's been too many years since I've had to justify those steps, so I don't remember the exact names of each property. They should be in your notes
anonymous
  • anonymous
alright, could you give me the reasons?
anonymous
  • anonymous
that match those statments u just gve me above?
anonymous
  • anonymous
no, sorry, it's too far in my memory. You should check in your notes or manual, the definition of each property should be there and it'll help you associate the properties (reasons) with the statements
anonymous

alrighty thanks:)

no problem!

We have the following Statments: 1) 2) 3) 4) 5) x = 15 Reasons: 1) Given 2) 3) 4) 5) So what is given here?
jim_thompson5910
  • jim_thompson5910
ie, what is the original problem?
anonymous
  • anonymous
I think that what you gave me should be flipped around like x=15 should be number five because I think its a whole problem.
anonymous
  • anonymous
The given is 3(x-4)=33 right?
jim_thompson5910
  • jim_thompson5910
good so that goes in statement 1) like this Statments: 1) 3(x-4)=33 2) 3) 4) 5) x = 15 Reasons: 1) Given 2) 3) 4) 5)
jim_thompson5910
  • jim_thompson5910
We have 2 options, we can either divide or distribute, but we're forced to distribute because there is no option that has x-4 = 11 (which would indicate division)
jim_thompson5910
  • jim_thompson5910
so this means we then get Statments: 1) 3(x-4)=33 2) 3x - 12 = 33 3) 4) 5) x = 15 Reasons: 1) Given 2) Distributive Property 3) 4) 5)
jim_thompson5910
  • jim_thompson5910
What's next?
anonymous
  • anonymous
fir statments wouldnt it be 3) 3x+0=45 4) 3x=45 right?
jim_thompson5910
  • jim_thompson5910
good
jim_thompson5910
  • jim_thompson5910
Statements: 1) 3(x-4)=33 2) 3x - 12 = 33 3) 3x + 0 = 45 4) 3x = 45 5) x = 15 Reasons: 1) Given 2) Distributive Property 3) 4) 5)
jim_thompson5910
  • jim_thompson5910
Now we just need 3 reasons for the last 3 statements
anonymous
  • anonymous
and then for reasons it would be 3) Subtraction Property of Equality 4)Additive Identity 5)Division Property of Equality right?
jim_thompson5910
  • jim_thompson5910
close, #3 is wrong though
jim_thompson5910
  • jim_thompson5910
3x - 12 = 33 3x - 12+12 = 33+12 ... Add 12 to both sides using the additive property of equality 3x + 0 = 45
anonymous
  • anonymous
I ment Addition Property of Equality
anonymous
  • anonymous
sorry lol
jim_thompson5910
  • jim_thompson5910
you got it Statements: 1) 3(x-4)=33 2) 3x - 12 = 33 3) 3x + 0 = 45 4) 3x = 45 5) x = 15 Reasons: 1) Given 2) Distributive Property 3) Addition Property of Equality 4) Additive Identity 5) Division Property of Equality
anonymous
  • anonymous
yay!!!!! lol
jim_thompson5910
  • jim_thompson5910
lol congrats
anonymous
  • anonymous
okay i have something that you could correct, will you check? 1) 5(x + 3) + 9 = 59 Given 2) 5x + 15 + 9 = 59 Distributive property 3) 5x + 24 = 59 additions property of equality 4) 5x + 0 = 35 subtraction property of equality 5) 5x = 35 addative identity 6) x = 7 division property of equality r these right?
anonymous
  • anonymous
@jim_thompson5910
jim_thompson5910
  • jim_thompson5910
3 is wrong
jim_thompson5910
  • jim_thompson5910
everything else is correct though
anonymous
  • anonymous
what would three be?
jim_thompson5910
  • jim_thompson5910
Is there a choice that says "combine like terms"? That's the most accurate description of what is going on in #3
anonymous
  • anonymous
no
anonymous
  • anonymous
here are the choices A. Reflexive Property B. Symmetric Property C. Transitive Property D. Addition Property of Equality E. Subtraction Property of Equality F. Multiplication Property of Equality G. Division Property of Equality H. Substitution Property I. Additive Identity J. Multiplicative Identity K. Commutative Property L. Associative Property M. Distributive Property N. Given
jim_thompson5910
  • jim_thompson5910
well, I guess the substitution property fits because you replace 15+9 with 24 and you can legally do this because 15+9 = 24
jim_thompson5910
  • jim_thompson5910
usually though, you'll just say "combine like terms" if you go from 15+9 to 24
anonymous
  • anonymous
yea but wouldnt that be 4?
jim_thompson5910
  • jim_thompson5910
4 is the subtraction (not substitution) property of equality
jim_thompson5910
  • jim_thompson5910
so you have that right
anonymous
  • anonymous
pooay so for three just put substitution in?
jim_thompson5910
  • jim_thompson5910
yeah that's what I would do given these options
jim_thompson5910
  • jim_thompson5910
personally, I'd say "combine like terms" since it fits better, but can't do that here
anonymous
  • anonymous
okay thanks so much!
