Question

Ruth Musser Middle School The length, I, of a wheelchair ramp is 13 more than 15 times its width, w. Which equation represents the relationship between the length and the width of the ramp?

A. L = 15w + 13
B. L = 15w - 13
C. L = 15 + 13w
D. L = 15 - 13w

Answer 1

The relationship between the length and width of a wheelchair ramp, where the length is 13 more than 15 times its width, is represented by the equation L = 15w + 13.

Step-by-step explanation:

The question is asking for an equation that represents the relationship between the length and the width of a wheelchair ramp, where the length is 13 more than 15 times its width. To express this relationship mathematically, we assign the variable L to represent the length of the ramp and w to represent the width of the ramp.

Following the given description, the equation can be written as:

L = 15w + 13

This equation shows that for every unit increase in width, the length increases by 15 units, and then we add on an extra 13 units to find the total length. Therefore, the correct equation that represents the relationship between the length and the width of the ramp is option A: L = 15w + 13.
