The outside temperature in a town is -20 degrees Fahrenheit. What change in temperature, in degrees Fahrenheit, would bring the outside temperature to 0 degrees Fahrenheit?

Answer :

To determine the change in temperature that would bring the outside temperature from [tex]-20^{\circ} \text{F}[/tex] to [tex]0^{\circ} \text{F}[/tex], we can use a simple subtraction method to find the difference between the two temperatures.

Step-by-step:

  1. Initial Temperature:

    • The initial temperature is [tex]-20^{\circ} \text{F}[/tex].

  2. Final Temperature:

    • The desired final temperature is [tex]0^{\circ} \text{F}[/tex].

  3. Calculate the Change in Temperature:

    • To find the change, subtract the initial temperature from the final temperature:
      [tex]0 - (-20) = 0 + 20 = 20[/tex]

Therefore, a change of [tex]20^{\circ} \text{F}[/tex] is needed to bring the outside temperature from [tex]-20^{\circ} \text{F}[/tex] to [tex]0^{\circ} \text{F}[/tex].

This means the temperature needs to increase by [tex]20^{\circ} \text{F}[/tex].
