I need help on 8-11 on page 19

8.) Part A: C

    Part B: B

9.) D

10.) 90degrees

11.) Part A: C

    Part B: B

Step-by-step explanation:

8.) 5x + 8 + 3x - 14 = 90

Combine Like Terms:

8x - 6 = 90

Subtract:

8x = 90

Divide:

x = 12

Plug x in :

5(12) + 8 = 68

3(12) - 14 = 22

9.) 7x + 10 = 12x - 75

    7x = 12x - 85

    5x = 85

    x = 17

    12(17) - 75 = 65

10.) 6x - 9 = 3x + 18

     3x - 9 = 18

     3x = 27

     x = 9

    6(9) - 9 = 45

    12(17) - 75 = 45

   45 + 45 = 90

11.) 6x - 9 + 3x + 18 = 180

     9x + 9 = 180

     9x = 171

     x = 19

     6(19) - 9

     114 -9 = 105

     3(19) + 18
