Hello!
You solve this algebraically
5x + 2(x - 4) = 5x + x - 10
Distribute the 2
5x + 2x - 8 = 5x + x - 10
combine like terms
7x - 8 = 6x - 10
subtract 6x from both sides
x - 8 = -10
Add 8 to both sides
x = -2
The answer is -2
Hope this helps!
Answer:

Step-by-step explanation:
Find the circumference.
C = dπ
C = 67(3.14)
C = 210.38
Since there are 14 revolutions, multiply the circumference by 14.
210.38 x 14 = 2945.32
Round
2,945
