To determine the number of inches per foot, we need to analyze the equation \(4y = 48x\).
In this equation,
- \(y\) represents the number of inches,
- \(x\) represents the number of feet.
Since we are specifically interested in how many inches there are in one foot, we can rewrite the equation like this:
-
Divide both sides of the equation by 4: \[ y = 12x \]
-
Now, if we want to find the number of inches for 1 foot (where \(x = 1\)): \[ y = 12 \times 1 = 12 \]
Thus, there are 12 inches in 1 foot.
