Please help me!! How do I do this?

Step-by-step explanation:

We are given that a cylinder container has a  height of 24 inches.

Currently, the container filled with water to a height=18 inches

If the height of the water in the container increase by 2 inches per hour

We are given that an equation which can be used to find the t in number of hours it would take to fill the container

We have to find the coefficient of t

In one hour, height increase=2 inches

In t hours, height increase=2t

According to question

Therefore, the coefficient of t is 2.

Hence, the number should be the coefficient of t=2
