At 3:30 am the temperature is -5 f. Between 3:00 am and 6:00 am the temperature drops by 12 f. Between 6:00 am and 9:00 am the temperature rises by 4 f. What is the temperature at 9:00 am?
-5f - 12f+4f = so now your going to add the common numbers which are -5 and -12 which equals -17 so now you have an equation of -17 + 4 which = 13 so your answer is 13. hope this helped !
