Question
There are 48 inches in 4 feet, which is represented by the equation 4y=48x
. Determine the number of inches per foot.(1 point)
inches

1 answer

To find the number of inches per foot from the equation \( 4y = 48x \), you can start by simplifying the equation.

  1. Divide both sides of the equation by 4:

\[ y = \frac{48}{4}x \]

  1. Simplifying this gives us:

\[ y = 12x \]

This means that for every 1 foot (represented by \( x \)), there are 12 inches (represented by \( y \)).

Thus, there are 12 inches per foot.
