<u>Step 2: Solve for </u><u><em>x</em></u>
- Factor:
- [Division Property of Equality] Divide 1 + a on both sides:
pool has 45000 gallons. It loses 780 gallons per hour, so the amount at any given time:
45000 - 780h, where h is the number of hours.
The chemical could be added once the amount of gallons in the pool hits 15000. So the equation to solve:
45000 - 780h = 15000
solve:
30000 = 780h
38.46 = h
It will take about 38.46 hours before chemical could be added. It will not take longer than 2 days because 2 days is 48 hours, and we only need about 38 hours.
Answer:
500+4=504

Answer:
The answer is x=16 so whatever the equations should look like it should be this:
Step-by-step explanation: 5(x-12)=20 5x-60=20 add 60 to 20 and get 5x=80 x=16
C = 2 pi r given r = 4
so
C = 2 pi (4)
C = 8 pi
answer
C. C = 8pi
