Question

A faucet leaks at a constant rate of 7 gallons per hour. Suppose y halons leak in x hour from 6:00am. Express the situation as a linear equation in two variables

Answer 1

The situation expressed as a linear equation in two variables is y = 7 × x

Explanation:

Here we have the rate of leakage of the faucet = 7 gallon per hour

Therefore, If y gallons leak in x hours from 6:00 am we have

Amount of gallons leaked = Gallons leaking per hour × Number of hours

Since our amount of gallons leaked is y gallons and

The number of hours of the leakage = x hours also

The leakage rate = 7 gallons per hour we then have;

y gallons leaked = 7 gallons/hour × x hours

The situation expressed as a linear equation in two variables =

y = 7 × x.
