The list below gives the maximum temperatures (in ° c), for each month of the year from january through december in fairbanks. what is the average of these monthly temperatures? round your answer to the nearest tenths place. -25, -20, -13, - 2, +9, +15, +17, +14, +7, -4, -16, -23 (paper due on 11/5/18)

To find the average sum the temperatures and divide by 12, the number of months

sum = - 25 - 20 - 13 - 2 + 9 + 15 + 17 + 14 + 7 - 4 - 16 - 23 = - 41

average = = - 3.42°C ( to nearest tenth )

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
