Answer 1

Answer:

D.

Step-by-step explanation:

Morena started at sea level, dove down 15 feet, then rose up 6 feet.

Answer 2

Answer:

0 + (-15) + 6 = -19. It is C. She started at sea level, dove down 15 feet, then 6 more feet.

Step-by-step explanation:

Morena dove 19 feet below sea level. That negative sign also means subtracting, so try this! 0 - 15 + 6. This equation makes it more simpler to solve.
