Answer:
A) 9
Step-by-step explanation:
R=7x+17
S=4x-6
Q=180-110=70
- 4x-6+7x+17+70=180
- 11x+81=190
- 11x=180-81
- 11x=99
- x=99/11
- x=9
Dependent variable would be the test scores, because they DEPEND on the amount of TV you watched
The answer would be $3 becaus of x = $12 and y = $9. $12 - $9 = $3.
