A. 6
B. 9
C. 1
D. 3

Answer 1

When a = 9 and b = 6, the expression (a - b) / 3 evaluates to (9 - 6)/3 = 3/3 = 1.

Therefore, the answer is C. 1.

Answer 2

You are saving for a skateboard. Your aunt gives you $45 to start and you save $3 each week. The expression 45+3w gives the amount of money you save after w weeks. How much will you have saved after 4 weeks?

A. $42
B. $57
C.$576
D $33

Answer 3

To find out how much money you will have saved after 4 weeks, we can substitute w = 4 into the expression 45 + 3w.

45 + 3(4) = 45 + 12 = 57

Therefore, you will have saved $57 after 4 weeks.

Therefore, the answer is B. $57.
