Algebra practice question

Answer: 14

Add 1 and halve: 2 ≤ x ≤ 5. The integers are 2, 3, 4, 5, whose sum is 14.

Common wrong answers

If you answered 4

4 is how many integers satisfy it, not their sum.

If you answered 9

9 omits x = 5.

If you answered 12

12 leaves out one endpoint; both endpoints are included because the inequalities are ≤.
