At noon, the average temperature on the moon is 112oc. during the night, the average temperature drops 252oc. what is the average temperature on the moon's surface during the night?

Average temperature at night -140°C.

Step-by-step explanation:

To find the average temperature at night we have to deduct the drop in temperature from the average temperature at noon.

Average temperature at night = Average temperature at noon - drop in temperature.

                                                  =112°C -  252°C

                                                  = -140°C

add 8+12 to get a simplified answer of 12r-20
