Use the cover up method so cover up 10x so it looks like 5y=15 divide it then you have y so plug it in and solve for x hope this helps

10x - 5y = 15       :Cover up the 10x so -5y is left

-5y = 15              :Then, divide the whole equation by -5

<em><u>y = -3</u></em>                 (To figure out x, do the opposite and cover up the -5y)

A pump fills a pool at the rate of 20 cubic meters in an hour. If each cubic meter of water costs $10, how many minutes will the
fomenos

The first thing any good mathematician does is convert the measurements to the same unit as what the question is asking. In this problem, it states that the pool fills at a rate of 20 cubic meters per hour. Just keep in mind that an hour is 60 minutes.

The next step is to see how many cubic meters will cost $300. This can be done by dividing 300 by 10. This gets you 30 cubic meters of water.

You already know that 60 minutes is 20 cubic meters of water. That leaves the remaining 10 cubic meters of water. By dividing the rate given, you get that 30 minutes is 10 cubic meters of water. Add the 60 and 30 together to get 90 minutes.

It will take 90 minutes for the pump to use $300.
