They are called powers of 10.
The answer is 390km. You just multiply 130 x 3.
a) Phoenix is 85, Juneau is -23
-23 to 0 is 23, 0 to 85 is 85. 85 23 = 108 total degrees hotter.
b) Milwaukee was -7, the temperature rose 12 degrees.
-7 + 12 = 5
It was 5 degrees at noon.

Hello from MrBillDoesMath!
Answer:
41 sqrt(3)
Discussion:
My first reaction to the problem was:
sqrt(27) = sqrt ( 3 * 9) = 3 sqrt(3) and
sqrt(48) = sqrt (3*16) = 4 sqrt(3).
So...
7 * sqrt(27) + 5 sqrt(48) =
7 * (3 sqrt(3)) + 5 * (4 sqrt(3)) =
21 sqrt(3) + 20 sqrt(3) =
41 sqrt(3)
