x = 5
Step-by-step explanation:
5x - 2x + 10 = 25
- 10 -10
5x - 2x = 15
3x = 15
divide 3 on both sides of the equal sign
x = 5
to check
5(5) - 2(5) + 10 = 25
25 - 10 + 10 = 25
25 = 25

Answer: it will take 576000 gallons to fill the lap pool.
Step-by-step explanation:
The formula for determining the volume of water in the rectangular pool is expressed as
Volume = length × width × height
The rectangular lap pool measures 80 feet long by 20 feet wide if it needs to be filled to 48. It means that the volume of water that would be pumped inside the pool is
Volume = 80 × 20 × 48 = 76800 cubic feet
1 cubic foot = 7.5 gallons
76800 cubic feet = 76800 × 7.5 = 576000 gallons
