Answer:
5x?
Step-by-step explanation:
Because Zachary earns $5 per hour, and he makes a $20 bonus.
His equation is shown in red on the graph, y = 5x + 20.
Maisy earns $7.50 per hour, and she makes a $5 bonus.
Her equation is shown in blue on the graph, y = 7.50x +
5.

Answer:
x=4.
Step-by-step explanation:
Let's solve your equation step-by-step.
5/15=x/ x+8
Step 1: Cross-multiply.
5/15=x/ x+8
5*(x+8)=x*(15)
5x+40=15x
Step 2: Subtract 15x from both sides.
5x+40−15x=15x−15x
−10x+40=0
Step 3: Subtract 40 from both sides.
−10x+40−40=0−40
−10x=−40
Step 4: Divide both sides by -10.
−10x−10=−40−10
Then your answer will be x=4.
