Answer:
39.9
Step-by-step explanation:
X = 1st job
y = 2nd job
x + y = 22......x = 22 - y
7x + 8.25y = 171.50
7(22 - y ) + 8.25y = 171.50
154 - 7y + 8.25y = 171.50
-7y + 8.25y = 171.50 - 154
1.25y = 17.50
y = 17.50 / 1.25
y = 14 <== 14 hrs at the 8.25 per hr job
x + y = 22
x + 14 = 22
x = 22 - 14
x = 8 <=== 8 hrs at the 7 per hr job
Hi there, I think I might be able to help,
C/4=-9
We can multiply by 4 on both sides to balance the equation
C/4 × 4= -9×4
C=-36
Hope that helped!
