Answer 1

The temperature in the morning was
`-10.5^o`

Explanation:

we know that

1) The high temperature in Fairbanks, Alaska was 15.7 degrees

That night it fell 38.4 degrees

so

The temperature at night was

`15.7^o-38.4^o=-22.7^o`

2) The next morning, it rose 12.2 degrees.

so

The temperature in the morning was

`-22.7^o+12.2=-10.5^o`
