Answer:
Step-by-step explanation:
9(c+7)=27
9c+63=27 subtract 63 from both sides
9c= -36 divide by 9
c= -4
3(2r-8)+4r=76 foil
6r-24+4r=76 combine like terms
10r-24=76 add 24 to both sides
10r+100 divide by 10
r= 10

Answer:
Slope = - 121
Hope This Helps :)
Answer:
-121X
Step-by-step explanation:

And you have to show your work Bc the dang teacher is strict
Answer:
I think the answer is 11.8
Step-by-step explanation:
25+ [ 15- 4 x 16/5] - 15.4
25 +[ 15- 4/1 x 16/5] - 15.4
25+ [ 15 - 20/5 x 16/5] - 15.4
25 +[ 15 - 64/5] - 15.4
25+ [ 15/1 - 64/5] - 15.4
25+ [75/5 - 64/5] - 15.4
25+ 11/5 - 15.4
25+ 2.2 - 15.4
27.2 - 15.4
11.8
