Answer:
C
Step-by-step explanation:
Add the like terms, the a's by themselves and b's by themselves.
8a+5a=13a
6b+2b=8b
so 13a+8b
C
2.4x+2.8=10
Use inverse operations to find for x!
x= 3
Answer:
Step-by-step explanation:
5x^2 - 2y.....x = 2 and y = 3
5(2^2) - 2(3) =
5(4) - 6 =
20 - 6 =

Answer:
![\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B9%7D)
Step-by-step explanation:
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.888.. (1) ← multiply both sides by 10
10x = 8.888.. (2)
subtract (1) from (2) thus eliminating the repeating digits
9x = 8 ( divide both sides by 9 )
x = ![\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B9%7D)
