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
  • tatumnolan
ok
anonymous
  • anonymous
in the outside would go a \(3\)
anonymous
  • anonymous
in other words, the top line would look like \[3(4n+9)-2\]

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

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

distribute the outer 3 through to each term inside the parenthesis |dw:1440464339206:dw|
jim_thompson5910
  • jim_thompson5910
notice how 3*4n = 12n which is already written by your teacher
tatumnolan
  • tatumnolan
sooooo... Im really sorry
jim_thompson5910
  • jim_thompson5910
do you see how 3*(4n+9) turned into 3*4n + 3*9 ??
anonymous
  • anonymous
@jim_thompson5910 distributed to get rid of the parentheses
jim_thompson5910
  • jim_thompson5910
yes
jim_thompson5910
  • jim_thompson5910
3 times 4n = 12n that part is already done for you
jim_thompson5910
  • jim_thompson5910
3 times 9 = ??
anonymous
  • anonymous
so now just multiply then divide
anonymous
  • anonymous
*27
anonymous
  • anonymous
now just divide 27 by 12
anonymous
  • anonymous
you get 2.25
anonymous
  • anonymous
this was a gift dude we were nice
anonymous
