Algebra practice question
Which of the following values of x satisfies x/2 − 1 > 3?
- A. 9Correct
- B. 8
- C. 6
- D. 4

x/2 − 1 > 3 means x/2 > 4, so x > 8. Only 9 qualifies: 4.5 − 1 = 3.5 > 3.
Why the other answers are wrong
- B. 8
- 8 gives 4 − 1 = 3, which is not GREATER than 3.
- C. 6
- 6 gives 3 − 1 = 2.
- D. 4
- 4 gives 2 − 1 = 1.
