Answer:

AB = 59

RS = 6

Explanation:

Hello!

21)

AB is the sum of AC and BC. We can solve for x and plug in the value to find AB.

Solve for x

  • 3x + 47 = x + 39 + 16
  • 3x + 47 = x + 55
  • 2x + 47 = 55
  • 2x = 8
  • x = 4

Solve for AB

  • 3x + 47 = AB
  • 3(4) + 47 = AB
  • 12 + 47 = AB
  • 59 = AB

AB is 59.

23)

RS is the difference of 30 and the sum of 9 and 15.

Solve for RS

  • 30 - (9 + 15) = RS
  • 30 -24 = RS
  • 6 = RS

RS is 6.
