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

Lelu [443]

Answer:

$-72$ 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 $2x$ .

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

$2x=-144$

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

$\frac{2x}{2}=\frac{-144}{2}$

$x=-72$

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