Translate the following into an algebraic expression: 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 pump work to use up $300.

For this case, the first thing we must do is define variables.

We have then:

x: number of minutes

y: total cost

We write the algebraic expression that models the problem.

We have then:

Simplifying we have:

Then, by the time the cost is equal to $ 300 we have:

From here, we clear the value of x.

an algebraic expression for the problem is:

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

w'x is 0.

hope it
