What I the answer to all 3

D: 15.75

A: -14.84

C: x = 11

Step-by-step explanation:

Two negatives make a positive, do 7.2 + 8.55 and you will get 15.75. If it's easier, do -10.5 + -4.34 to get -14.84. For number three you have to distribute 1/2 to x and 1 to get 0.5x + 0.5 = -5. Subtract -0.5 on both sides to get 0.5x = 5.5. Divide 0.5 from both sides to get 11.

p < 9

Step-by-step explanation:

5p-13<32

Subtract 13 from both sides.

5p<45

divide 5 from both sides

p < 9
