Alright, lets get started.
The temperature outside dropped 13 F.
Suppose the starting temperature = x
The final temperature is given a s= -2 F
Final temp = starting temp - drop in temp
[tex]-2 = x - 13[/tex]
Adding 13 in both sides
[tex]-2 + 13 = x - 13 + 13[/tex]
[tex]x = 11[/tex]
It means the starting temperature was 11 F. : Answer
Hope it will help :)
