How much longer will it take her to fill the tank write an equation to help answer the question choose the correct form below and fill in the blanks using only three 130 and 280 the valuable x is used to represent the number of minutes

Let x represent the number of minutes. We need to find the number of minutes it will take Ann to fill the remaining 280 - 130 = 150 gallons of water.

The equation that represents the situation is:

3x = 150
