Question

question: in a science experiment, the initial temperature was 55 degrees fahrenheit, and each hour after, the temperature dropped by 4 degrees. which expression represents the temperature, in degrees fahrenheit, after t hours? 55 - 4t 55 + 4t 4t + 55

Explanation:

Step1: Identify initial temperature

The initial temperature is 55 degrees Fahrenheit.

Step2: Determine temperature drop per hour

The temperature drops by 4 degrees per hour. After t hours, the total drop is 4t degrees.

Step3: Find final - temperature expression

We subtract the total drop from the initial temperature. So the temperature after t hours is $55 - 4t$.

Answer:

$55 - 4t$
