Answer:
Noa hiked 2 mi up a mountain trail and then hiked 2 mi down a trail
A hot air balloon ascended 2000 ft from the ground and then descends 2,000 ft
Explanation:
The additive inverses should be that
if a number i.e. a so it would be inverse like -a
And the sum of both would be zero i.e.
a + (-a) = 0
Now going through the options given
1st option should be
2 + (-2) = 0
This shows the additive inverses
The second option be
= + 3+ (-2)
= 3 - 2
= 1
The third option is
= 2000 + (-2000)
= 0 ft
This shows the additive inverses
The fourth option is
= -$70 + $100
= $30
Therefore the first and third option is additive inverses
