and I am really worried I am going to mess up

- anonymous

i am going to make a guess

- tatumnolan

I cant take a guess man

`jeez i got a headache just looking at this `
I agree. They couldn't have made this more convoluted

- anonymous

9 more than four times jenny's number
if we call jenny''s number \(n\) then that would be \(4n+9\) to go in the inside parentheses

- tatumnolan

ok

- anonymous

in the outside would go a \(3\)

- anonymous

in other words, the top line would look like \[3(4n+9)-2\]

- tatumnolan

ok Ive got that

- anonymous

normally it is a bad idea to give out direct answer, but frankly (not to boast) if it takes me ten minutes to understand the wording, lets call it a gift

- tatumnolan

THank you

- anonymous

last step is to multiply out and combine like terms to get the bottom answers

- jim_thompson5910

Let
R = robbie's number
J = jenny's number
K = kylie's number
W = willie's number
we know that Jenny made 'n' her number
"Robbie picked a number that is nine more than four times Jennie's number" means that R = 4n+9
----------------
For Willie, it says "Willie picked a number that is two less than three times Robbie's number" telling us W = 3R - 2
From here you replace the R with 4n+9 because the two are equivalent, so you should have
3(4n+9) - 2

FLVS<<

- tatumnolan

so confuzzled

- tatumnolan

so 12n + ?

- tatumnolan

the other ones werent this hard

- jim_thompson5910

|dw:1440464298754:dw|

- jim_thompson5910

distribute the outer 3 through to each term inside the parenthesis
|dw:1440464339206:dw|

- jim_thompson5910

notice how 3*4n = 12n which is already written by your teacher

- tatumnolan

sooooo... Im really sorry

- jim_thompson5910

do you see how 3*(4n+9) turned into 3*4n + 3*9 ??

- anonymous

@jim_thompson5910 distributed to get rid of the parentheses

- jim_thompson5910

yes

- jim_thompson5910

3 times 4n = 12n
that part is already done for you

- jim_thompson5910

3 times 9 = ??

- anonymous

so now just multiply then divide

- anonymous

*27

- anonymous

now just divide 27 by 12

- anonymous

you get 2.25

- anonymous

this was a gift dude we were nice

- anonymous

x=2.25
