Question

The relationship between feet and inches is described by the equation y = 12x, where x = a given length in feet and y = the equivalent length in inches. If a desk is 5.75 feet long, what is its length in inches?

Answer 1

replace x with 5.75 feet

y = 12(5.75)

12 * 5.75 = 69

 the desk is 69 inches long
