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.

Simplify by combining terms.

2x + 3(x – 2) – 3(x – 6)

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

2x + 12

Can you please herlp me with this too?

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
