Answer:
C (0.9)
Step-by-step explanation:
Key skills needed: Solving one variable equations
1) we have the equation --> 12.72 = 5.52 + 8x
2) We need to solve for x.
To get x by itself, we subtract 5.52 from both sides. (12.72 - 5.52 = 7.2)
This means 8x = 7.2
3) Divide by 8 from both sides, and you will get x = 0.9 (7.2/8 = 0.9)
