She already paid $5, and then she bowled 4 games so 4x represents the four games she bowled and how much she payed for them. The total cost was 18.
5 + 4x = 18
Subtract 5 from both sides:
4x = 13
Divide both sides by 4
x = 3.25
So she paid $3.25 per game
21/9 + 74/9 = (21 + 74)/9 = 95/9 = 10 5/9
Answer:
2
Step-by-step explanation:
Graph: look halfway between x= 4 and x=6, the point is on the line f(x)=2
Equation: (x-5) = (5-5) =0
anything times 0 is 0
0 +2=2
