Alexandra Armstrong · Answer 1

-37 meters

Step-by-step explanation:

75 + (-112) = -37

Rylee Cobb · Answer 2

-37 meters

Step-by-step explanation:

If the hiker started at sea level, his altitude would start at 0. Then, if he hikes 75 meters higher, his altitude would now be 75, since it's in the positive direction. But if he hikes downwards and decreases his altitude by 112, since 112 is bigger than 75, the number would be in the negatives. This would give you this equation (f meaning final altitude):

(0 + 75) - 112 = f

75 - 112 = f

-37 = f
