d. and ii

Step-by-step explanation:

a. [tex]-\frac{3}{2}[/tex]x + 12 > 15 = x > -2

           - 12  - 12

 [tex]-\frac{3}{2}[/tex]x > 3

2(  [tex]-\frac{3}{2}[/tex]x = 3)

-3x > 6

/-3    /-3

x > -2

b. 4x + 12 < 20 = x <2

        - 12   - 12

 4x < 8

 /4    /4

  x < 2

c. -8x < 16 = x > -2

   / -8   /-8

  x > -2

d. 55 < 35 + 10x = x > 2

  -35   -35

   20 < 10x

   /10   /10

   2 < x = x > 2

Hope that helps!
