Question

pls help

Answer 1

I feel like we're missing a part of the question. Like what is it actually asking?

Answer 2

It is asking: What is the final elevation

Answer 3

Okay. Assuming a positive difference is a upward change in verticality, and a negative difference is a downward change, then you can basically just do addition to find the answer.

Answer 4

So a. would be: 20 + 16

then b would be: 20 + -16 which simplifies to: 20 - 16.

Answer 5

Tysm!

Answer 6

Yeah, as long as you know your way around negative numbers, you can just add across then you should be fine.
