Question 1078952
For the last five days the average temperature was 63F. If the temperature for the first four days were 56'f,60'f,79'f,70'f what was the temperature for the fifth day? Can you show me how to solve that. 
-------
Average for 5 days = 63 degrees
--------------------------
(56 + 60 + 79 + 70 + x)/5 = 63
-----------------
265+x = 315
x = 50 degrees (temp on the day 5)
