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.

$\frac{1}{3} (n + 15) = -2$

First, replace the numerator with the parentheses.
$\frac{n+15}{3} =-2$
Second, multiply both sides by 3.
$n + 15 = -2 * 3$
Third, multiply 2 × 3 to get 6.
$n + 15 = -6$
Fourth, take away 15 from each side.
$n = -6 - 15$
Fifth, simplify -6 - 15 to get -21.
$n = -21$

Answer: n = -21

In a shipment of onions, 12% are damaged. 1,144 onions are undamaged.

katovenus [111]

Since 12% of them are damaged, that means the percentage of them that aren't 88%.
The easiest way to do it is to divide 88 from 1,144, written as 1,144<span>÷88.
That's 13. So, then you would multiply 13 by 100. To get the total amount of onions. That'd be 1,300.</span>
