Answer: 7 / 8 should be added
Step-by-step explanation:
Let x be the number that should be added
Write the equation
-3/2 + x = -5/8
Add -3/2 on both sides
-3/2 + x + 3/2 = -5/8 + 3/2
x = -5/8 + 3/2
Change the denominator of 3/2 to 8 in order to do addition
x = -5/8 + 12 / 8
x = 7 / 8
Hope this helps!! :)
Please let me know if you have any questions
For number one the answer is: X = 30
For number two the answer is: All real numbers are solutions.
For number three the answer is: There are no solutions.
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.
