Question: 139
4. 
- A. The quantity in Column A is greater.
- B. The quantity in Column B is greater.
- C. The two quantities are equal.
- D. The relationship cannot be determined from the information given.
Correct Answer: D
Explanation:
The answer is D
You need to solve for two cases. First, solve x - 2 > 9. Add 2 to both sides: x > 11. Now solve x - 2 < -9. Add 2 to both sides: x < -7. As x can be greater than 11 or less than -7, the relative size of the columns cannot be determined.
