if the temperature is -40 degrees fahrenheit and increases 20 degrees fahrenheit after an hour. what is the current temperature?

I'd say -40 + 20 = -20

-20 is the answer.

To find the current temperature, you need to add the increase of 20 degrees Fahrenheit to the starting temperature of -40 degrees Fahrenheit. Here's the step-by-step process:

1. Start with the temperature of -40 degrees Fahrenheit.
2. Add the increase of 20 degrees Fahrenheit.
- (-40) + 20 = -20
3. The current temperature is -20 degrees Fahrenheit.

Therefore, the current temperature is -20 degrees Fahrenheit.
