A submarine was 144 feet below sea level. A shark was hovering at a constant depth above the submarine. The submarine’s depth was twice the depth of the shark.

Which integer expression describes the position of the shark in relation to sea level?

feet : Shark is 72 feet below sea level.

Step-by-step explanation:

Let x represent depth of the shark.

We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be .

We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be .We can represent this information in an equation as:

To find shark's position, we need to solve for x.

Therefore, feet represents shark's elevation, which represents that shark is 72 feet below sea level.
