A rectangle has an area of 155 square inches. The length of the rectangle is 4 inches less than 7 times the width of the rectangle. What is the width of the rectangle, in inches?
Correct answer: A. 5
- A. 5
- B. 8
- C. 10
- D. 15
Explanation
The correct answer is 5. Let x represent the width of the rectangle. The length is 7x - 4. The area is calculated as x(7x - 4) = 155. Solving this equation gives x = 5 as the width. Option B, C, and D are incorrect as they result in areas that do not match the given area of 155 square inches.
