7. 2x + 3(x – 2) – 3(x – 6) (1 point)

2x + 12
2x – 8
8x – 24
2x – 24

I do not understand how to do this.

• Math help please Ms. Sue -

Simplify by combining terms.

2x + 3(x – 2) – 3(x – 6)

2x + 3x - 6 - 3x + 18

2x + 12

A baseball bat and 8 baseballs cost \$163.25. The bat costs \$106.45. What is the cost c of one baseball? (1 point)

163.25 – 8c = 106.45; \$33.71
8c + 106.45 = 163.25; \$7.10
8c + 163.25 = 106.45; \$7.10
8c – 106.45 = 163.25; \$33.71
