Question

the highest temperature in Denver is -23.7 on February 7. the highest temperature the next day was 5 warmer. what was the next day high temoerature

Answer 1

The next day high temperature will be -18.7

The temperature will be considered as 'warmer' as the temperature increased and will be considered as 'colder' if the temperature decreased.
So, if the temperature for the next day is 5 degrees warmer, then it must be:

-23.7 + 5 = -18.7 Degree
