Wait which 1 are yhu answering?
First find the volume of the pool. To do so, multiply the length, times the width, times the height. In this case, it would be 12*15*5 and you get 900 cubic meters.
If the pool is being filled with 36 cubic meters of water per hour, you divide 900 by 36. You get 25 hours.
To check your work, multiply 25 hours and 36 cubic meters of water. You get 900 cubic meters, which is the area of the pool meaning it is full.
Answer: no solutions.
Step-by-step explanation:
get y by itself on one equation.
-4x + y = 3 ... add 4x to each side.
y = 4x + 3
plug in 4x + 3 for y in the other equation.
8x - 2y = 1
8x - 2(4x+ 3) = 1 ... plug in the y value
8x - 8x + 3 = 1 ... distribute the 2
3 = 1 ... solve
3 does not equal 1 so it is no solutions.
Answer:
The plumber charges £16.50 per hour. this is how to solve it. You minus the callout fee from the total fee which is £167.00- £18.50=£148.50. So you then divide 148.50 by the amount of hours which is 9 hours. so 148.50÷9 = £16.50
