Answer:

  • D. 15

Step-by-step explanation:

<u>First find the value of x:</u>

  • 3x - 16 + 6x + 7 = 180 (supplementary angles)
  • 9x = 189
  • x = 21

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

  • 11y - 32 = 6x + 7 (vertical angles)
  • 11y - 32 = 6*21 + 7
  • 11y = 32 + 133
  • 11y = 165
  • y = 165/11
  • y = 15

Answer:

x=1

Step-by-step explanation:

Expand the brackets by multiplying each term in the bracket by the expression outside the bracket:

    3(4x-5)-4x+1=-6

⇒  12x-15-4x+1=-6

Gather like terms and combine:

⇒  12x-4x+1-15=-6

⇒  8x-14=-6

Add 14 to each side of the equation:

⇒  8x-14+14=-6+14

⇒  8x=8

Divide both sides by 8:

 ⇒  8x \div8=8\div8

⇒  x=1
