Answer:
-3
Step-by-step explanation:
At 7 it was 4⁰F
At 8 it would be 4⁰F-2.6⁰F=1.4⁰F
At 9 it would be 1.4⁰F+1.3⁰F=2.7⁰F
At 10 it would be 2.7⁰F-5.7⁰F = -3⁰F
Answer:
-3 degrees
Step-by-step explanation:
At 7:00 pm the temperature was 4 degrees. To find the temperatuer at 10:00 pm, we must apply all of the changes that occured throughout the hours until 10:00 pm.
4 - 2.6 = 1.4
1.4 + 1.3 = 2.7
2.7 - 5.7 = -3
From this, we can see that the temperature at 10:00 pm was -3 degrees F.
hope this helps!
