• A temperature of −8 degrees C is 3 degrees warmer than a temperature of -5 degrees C.

• A balance of -40 dollars, means that you owe $40.

• Elevations of -50ft and 50ft are the same distance from sea level

-Submarine F is 39.6 feet below sea level

-Submarine G is 19.5 feet below sea level

-Submarine H is 57.8 feet below sea level

Select all answers that are true.

• Submarine F is deeper than submarine G

  because l-39.6l > l-19.5l

• Submarine G is deeper than Submarine H

  because ∣−19.5∣ > ∣−57.8∣

• Submarine F is deeper than Submarine H

  because |-39.6l >l-57.8l
