Apartially-filled water tank contains 300 gallons of water. water is the pumped into the rank at a constant rate. after n minutes, the amount of water, w, in the tabk is w = 300+gngallons. after how many minutes will w = 450gallons ?

After the tank will have 450 gallons of water.

Step-by-step explanation:

Volume of water in tank = 300 gal

Rate at which water was pumped in tank = g

The function representing amount of water after n minutes:W

Given, W = 450 at n =?

After the tank will have 450 gallons of water.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
