Let her score on her math test be y and the number of hours a week that she plays video games be x,
y = k/x
73.6 = k/10
k = 736
y = 736/x
y = 736/8
y = 92
She can expect a score of 92 on her math test if she plays video games for only 8 hours a week.
Answer:
True.
Step-by-step explanation:
Let x = 1
y = 1/5(1) + 4/5
= 1/5 + 4/5
y = 5/5 = 1
Therefore, this statement is true.
Answer:
-9/4 = x
Step-by-step explanation:

7 = 4(x+4)
7 = 4x + 16
-9 = 4x
-9/4 = x
