Mai's fish tank has 18 liters of water in it. She plans to add 4 liters per minute until the tank has more than 54 liters. What are the possible numbers of minutes Mai could add water?
Use t for the number of minutes.
Write your answer as an inequality solved for .
The inequality that represents the given situation is 18 + 4t > 54.
To solve for t, we can subtract 18 from both sides of the inequality:
4t > 36.
Finally, we can divide both sides of the inequality by 4 to solve for t:
t > 9.
Therefore, the possible numbers of minutes Mai could add water are t > 9.
Let's set up an equation to represent the volume of water in the tank at any given minute, t:
18 + 4t > 54
To solve this inequality for t, we can isolate the variable:
4t > 54 - 18
4t > 36
t > 36/4
t > 9
So, the possible numbers of minutes Mai could add water are t > 9.
To find the possible numbers of minutes Mai could add water, we need to set up an inequality and solve for t.
From the given information, we know that Mai plans to add 4 liters per minute until the tank has more than 54 liters.
Let's set up the inequality:
18 + 4t > 54
Now, let's solve for t:
18 + 4t > 54
Subtract 18 from both sides:
4t > 54 - 18
4t > 36
Divide both sides by 4:
t > 36 / 4
t > 9
So, the inequality that represents the possible number of minutes Mai could add water is t > 9.
