Step-by-step explanation:
at noon x°F.
at midnight we had -7.2°F.
-7.2 = x - 23.8
x = -7.2 + 23.8 = 16.6°F
Considering the temperature at midnight, it is found that the temperature at noon was of 16.6ºF.
Between noon and midnight, the temperature went down by 23.8°F, meaning that the temperature at noon is the midnight's temperature if -7.2 ºF added to 23.8 ºF, hence:
-7.2 + 23.8 = 16.6ºF.
The temperature at noon was of 16.6ºF.
