Question

The temperature in the arctic circle at 9:00 a.m. was -28 F by 6:00 on the same day the temperature had decreased by 16 degrees what was the temperature after the decrease

Answer 1

Answer:

-44° F

Step-by-step explanation:

In order to get the temperature after the decrease, we need to subtract 16 from -28. You can write this as -28 - 16, or (-28) + (-16) because subtracting a positive number from a negative number is just like adding two negative numbers.

Furthermore, adding negative numbers is just like adding positive numbers, but just with a negative sign. So, (-28) + (-16) = -44.
