Question

a leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours. after the leak is fixed, the height of
the water is 4.75 feet. the equation 4.75 = x + (-0.25) can be used to find x, the original height of the water in a pool.
what was the original height of the water in the pool in feet?
a 4.5
b 5.0
c 6.5
d 7.0

Explanation:

Step1: Solve the equation for x

The equation is \( 4.75 = x + (-0.25) \), which is equivalent to \( 4.75 = x - 0.25 \). To solve for \( x \), we add \( 0.25 \) to both sides of the equation.
