Question

If the 6am temperature in Durango, Colorado was -8° F and the temperature rose 15° by 2pm, then what would the temperature be at 2pm?

Answer 1

Hello there! Given the temperature at 6am in Durango, Colorado was -8° Fahrenheit:

-8° + 15° = temperature at 2pm

• When adding a positive to a negative, we are subtracting the numbers and taking the sign of the greater number. The equation is represented as so:

(-) + (+) = (+)

The general rule corresponding to this equation is that the answer acquires the sign of the greater number. In this case, because 15 is greater than 8, our answer will be a positive number.

-8 + 15 = 7

From 6am to 2pm, the temperature would have risen from -8° Fahrenheit to 7° Fahrenheit. If you need any extra help, let me know and I will gladly assist you.
