Question

The temperature falls from 3°C to -4°C. What is the difference in these temperatures?

Answer 1

-1

Explanation:

3- 4 = -1

Answer 2

Answer: 7°C

Explanation:

1. Set up the equation. 3°C-x=-4°C.

2. Isolate x. So, subtract 3°C from both sides. -x=-7°C.

3. Divide both sides by -1. x=7°C.
