Question

The water level in the aquarium's shark tank is always greater than 25 feet. If the water level decreases by 6 feet during cleaning, what was the water level before the cleaners took out any water?

Answer 1

Answer:

Greater than 31 feet.

Step-by-step explanation:

Let x be the water level before the cleaners took out any water.

Now, the water level decreased by  6 feet during cleaning.

Hence, the water level after cleaning is x -6

Now, it has been given that water level in the aquarium's shark tank is always greater than 25 feet

Thus, the inequality for the situation is

$x-6>25$

Add 6 to both sides

$x>25+6\\x>31$

Hence, the water level before the cleaners took out any water was greater than 31 feet.
