Question

Awater tank is filled with 550 gallons of water. The water is draining out at a rate of 30 gallons per hour. Write an equation for the time it will take for all water to drain (y) in relation to the time passed (x).

Answer 1

The equation for the time it will take for all water to drain from the tank in relation to the time passed is y = 550 - 30x.

Step-by-step explanation:

To find the time it will take for all the water to drain from the tank (y) in relation to the time passed (x), we can use the formula:

y = 550 - 30x

Where y represents the amount of water remaining in the tank and x represents the time passed in hours. The equation is obtained by subtracting the rate at which the water is draining (30 gallons per hour) from the initial amount of water in the tank (550 gallons).
