Question: 394
5. 
If the line segment AB is 24 meters long, based on the figure, how long is line segment CB?
- A. 6 m
- B. 8 m
- C. 12 m
- D. 16 m
Correct Answer: D
Explanation:
D
Set up an equation: 2s + 4s = 24. Combine like terms and divide by 6: s = 4. Plug 4 into 4s: 16.
Test the answers, starting with choice (C). If 4s = 8, then s = 2, and 2s = 4. As 4 + 8 is less than 24, eliminate choice (C) as well as choices (A) and (B). Try choice (D). If 4s = 16, then s = 4, and 2s = 8. As 8 + 16 = 24, choice (D) is correct.
