Question

A submarine was 200 feet below sea level. It then descended 130 mcre feet. What is the new depth?

Answer 1

If something goes below sea level, that means the answer is gunna be a negative number. so we have -200 and -130. we have to add the numbers together.

-200 + -130 = -330.

The new depth is -330. Hope this helps. Let me know if you need anymore help!

Answer 2

Sea level = 0
↳ So any mesures below sea level are in the negatives!

⓵ You were at -200 feet before it descended 130 feet :

× = new depth

Your equation:

-200 - 130 = ×

⓶ Now all you have to do is solve your equation!

-200 - 130 = ×

-330 = ×

→ The new depth is 330 feet below sea level!

There you go! I really hope this helped, if there’s anything just let me know! ☻
