Mathematics

Set up a ratio:

5/3 = 40 / 2x+10

Cross multiply:

5(2x+10) = 3(40)

Simplify:

10x+50 = 120

Subtract 50 from each side:

10x = 70

Divide both sides by 10:

x = 70/10

x = 7

<u>Find the value of x:</u>

  • 7x - 2 = 55 + 4x (as corresponding angles)
  • 7x - 4x = 55 + 3
  • 3x = 57
  • x = 19

<u>Find the value of y:</u>

  • y = 7x - 2 (as alternate exterior angles)
  • y = 7*19 - 2
  • y = 131
<h3>#30</h3>

<u>Find the value of x:</u>

  • 14x - 34 = 9x + 1 (as alternate interior angles)
  • 14x - 9x = 1 + 34
  • 5x = 35
  • x = 7

<u>Find the value of y:</u>

  • y + (9x + 1) = 90 (as complementary angles)
  • y = 90 - 9*7 - 1
  • y = 26
