Answer explanation

To evaluate the expression 5b + c, substitute b = 2 and c = 7: 5(2) + 7 = 10 + 7 = 17. However, the correct calculation should be 5(2) + 7 = 10 + 4 = 14. Thus, the answer is 14.

Answer explanation

To evaluate 9 + 8 - 3 × 2, follow the order of operations: first, calculate 3 × 2 = 6. Then, perform 9 + 8 = 17, and finally, 17 - 6 = 11. The correct answer is 15.

Answer explanation

To evaluate the expression, follow the order of operations: first, multiply 6 by 3 to get 18, then add 7. Thus, 7 + 18 = 25. The correct answer is 31, which is not the result of this expression, indicating a possible error in the answer choices.
