The temperature at 9 AM was 13°F, If the temperature is -2°F at 6 AM and the next three hours the temperature increases 15°F.
Explanation:
The given is,
Temperature is -2°F at 6 AM
For the next three hours from 6 AM the temperature increases 15°F
Step:1
We need to find the temperature at 9 AM,
Let, X - Temperature at 6 AM
Y - Temperature at 9 AM
Step:2
Where,
X = -2°F
From the given, Y becomes
( during the next three hours the temperature increases 15°F )
Y = X + 15
Substitute the X value,
= (-2 + 15)
Y = 13°F
Result:
Thus the temperature at 9 AM was 13°F, If the temperature is -2°F at 6 AM and the next three hours the temperature increases 15°F.
