The temperature started at 12 degrees Fahrenheit. The temperature dropped 5 degrees every hour. What was the temperature after 4 hours
12 °F - 5 °F ∙ 4 = 12 °F - 20 °F = - 8 °F
To find the temperature after 4 hours, you can subtract 5 degrees for every hour from the initial temperature of 12 degrees Fahrenheit.
Step 1: Start with the initial temperature of 12 degrees Fahrenheit.
Step 2: Subtract 5 degrees for every hour for a total of 4 hours.
12 degrees Fahrenheit - 5 degrees/hour * 4 hours = 12 degrees Fahrenheit - 20 degrees = -8 degrees Fahrenheit.
Therefore, the temperature after 4 hours is -8 degrees Fahrenheit.
To find the temperature after 4 hours, we need to subtract 5 degrees Fahrenheit for each hour that passed.
Starting with a temperature of 12 degrees Fahrenheit, we subtract 5 degrees Fahrenheit for each of the 4 hours.
First hour: 12 - 5 = 7 degrees Fahrenheit
Second hour: 7 - 5 = 2 degrees Fahrenheit
Third hour: 2 - 5 = -3 degrees Fahrenheit
Fourth hour: -3 - 5 = -8 degrees Fahrenheit
So, after 4 hours, the temperature would be -8 degrees Fahrenheit.
