8) C

9) -34.72

10) B

12) -0.83 pounds

18) $13.75

Step-by-step explanation:

8) 2/3m = 4/6m

4/6m + 5/6m = 9/6m = 1 1/2m

-1 1/6 + -1 1/3 = -2 1/2

9) -44.84 - 24.6 = -69.44

-69.44 ÷ 2 = -34.72

10) -4°F + 4°F

12) -1.56 + 0.73 = -0.83

18) 1,500 × 0.16 = 240

515 - 240 = 275

275 ÷ 20 = 13.75

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
