Guess. it's what the question is asking you to do.

Answer 11

whats the answer though

Answer 12

Estimate: It is about 80-10, which is 70. To refine the estimate, we might say that we started 3/2 less than 80, and took off 1/2 less than 10, so our refined estimate is one more, or 71. The actual (exact) answer is a touch bigger than that.

Answer 13

thank you

Answer 14

3 • (8 + 2) = 3 • (2 + 8)
2 • (5 • 17) + 12 = (2 • 5) • 17 + 12

2 • (8 + 9) = 2 • 8 + 2 • 9

4 • (7 + 0) = 4 • 7
