I think the answer would be 54 for X
Hello!
so we just need to raise the pool back to original level
in total, the pool drained a total of 1 and 3/8 inches
so we need to find out how long it would take to raise the pool by 1 and 3/8 inches
1 inch=320 gallons
1 and 3/8=320 times 1 and 3/8=320 and 960/8=440
he needs to put in 440 gallons
it is 5.75 gallons per minute
find out how many minutes it will take
440=5.75 times x minutes
divide both sides by 5.75
76.521=xminutes
round
77 minutes
1 hour=60 minutes
77>60
it will take more than 1 hour to make the pool back to original level
Hope this Helps! Have A Wonderful Day! :)
Answer:
Dilation
Step-by-step explanation:
Step-by-step explanation:
solve simultaneously
subtract the 2 equations like you subtract pure numbers from each other.
5x + 2y = 12
3x + 2y = 8
5x - 3x +2y - 2y = 12 - 8
2x = 4
x = 2
alternatively...
3x + 2y = 8
5x + 2y = 12
-2x = -4
x = 2.
