Which real-world story is represented by the addition problem (–2 1/2) + (–3 1/4) = –5 3/4?

brainliest gets 20 points

a. a submarine descended 2 1/2 miles and then descended another 3 1/4 miles. the submarine is now 5 3/4 miles below its original location.

b. a submarine ascended 2 1/2 miles and then descended another 3 1/4 miles. the submarine is now 5 3/4 mile below its original location.

c. a submarine descended 2 1/2 miles and then ascended another 3 1/4 miles. the submarine is now 5 3/4 mile above its original location.

d. a submarine ascended 2 1/2 miles and then ascended another 3 1/4 miles. the submarine is now 5 3/4 miles above its original location.

A

Step-by-step explanation:

A is the correct answer because the equation matches option A.

(-2 1/2) + (-3 1/4)

The minus sign in -2 1/2 shows that the submarine descended and then descended again with the addition sign. Though the addition sign can mean that it ascended its incorrect.

With the equation in hand, we can prove that option A is correct.

If the submarine descended 2 1/2 miles then here must be a minus sign next to the 2 1/2. But if it ascended then there would've been an addition sign to show that it ascended. The other value - 3 1/4 also shows that it ascended with the help of the addition sign.

Ascends - values increase from smallest to highest.

Descends - values decrease from highest to smallest.

based on context clues you gave i'm assuming the answer would be c.
