Question

Which statements include two quantities in the real world that are additive inverses?

Answer 1

Answer:

The options are (2) and (4).

Step-by-step explanation:

2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.

→ Up 2 mi (+2) and down 2 mi (-2).

4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

→ Here they are, ascends 2000 ft (+2000) and descends 2000 ft (-2000).

Answer 2

Answer :

There are two statements here, showing quantities in real world which are additive inverse of each other :

2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.

here, we can depict going up as +2 miles and going down the trail as -2

4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .
