Mr. Piper's plumbing needed repairs. The plumber charged $98 for parts plus $45 per hour for labor. If the bill totaled $458, how could I find out the hours of labored required?

• 98x + 45 = 458

• 98 + 45x = 458

• 45 + 98 = 458

• 45x - 98 = 458

• -2

• 2

• 4

• -3

What is the first step to solve the following equation?

-2|x + 3| = -10

• Set up 2 equations

  -2(x + 3) = 10

  -2(x + 3) = -10

• Add 2 to both sides

• Subtract 3 from both sides

• Divide by -2 on both sides

• No Solution

Solve:
C = 2πr, for r

• C/(2π) = r

• C + 2π = r

• C - 2π = r

• 2πC = r
