Answer :
The original height of the water level in pool is 5 feet
Solution:
Given that , 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.
So by solving the given equation and finding value of "x" gives the original height of water in pool
We have to find the original height of the water level in the tank.
So, let us solve the given equation
[tex]\begin{array}{l}{\rightarrow 4.75=x+(-0.25)} \\\\ {\rightarrow 4.75=x-0.25} \\\\ {\rightarrow x=4.75+0.25} \\\\ {\rightarrow x=5}\end{array}[/tex]
Hence, the original height of the water level is 5 feet
