Answer:
The temperature in the morning was [tex]-10.5^o[/tex]
Step-by-step 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
[tex]15.7^o-38.4^o=-22.7^o[/tex]
2) The next morning, it rose 12.2 degrees.
so
The temperature in the morning was
[tex]-22.7^o+12.2=-10.5^o[/tex]
