Tank A initially contained 124 liters of water. It is then filled with more water, at a constant rate of 9 liters per minute.

How many minutes have passed, `m`, when Tank A contains the following amounts of water?

Show or explain your reasoning.

The following amounts of water have not been listed.

However, to find m all you need to do it;

the amount of water which is in the tank - 124 = x

x ÷ 9 = m

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
