Question

The number of feet y in a measure varies directly as the number of meters x. Write a direct variation equation that can be used to convert feet to meters, if 4 feet is about 1.25 meters.

Answer 1

Answer:

Step-by-step explanation:

“y varies directly as x”

y = kx

Plug in (4, 1.25) and solve for k:

1.25 = 4k

k = 1.25/4 = 0.3125

The equation becomes

y = 0.3125x
