An easy way to do this is find the absolute value of both numbers and add them together which will yield your range. The absolute value of a number is the amount of whole numbers away it is from 0. 20 is 20 away from 0, and -25 is 25 away from 0. Now we just add 25 and 20, which equals 45. Therefore, this temperature changed by 45 degrees.

Answer:

[tex]45^{\circ}[/tex]  

Step-by-step explanation:

Given :One winter day, the temperature ranged from a high of 20 degrees Fahrenheit to a low of negative 25 degrees Fahrenheit.

To Find :By how many degrees did the temperature change

Solution :

Initial temperature = 20°

Final temperature = -25°

Change in temperature = [tex]20^{\circ}-(-25}^{\circ})[/tex]

                                        = [tex]45^{\circ}[/tex]  

Hence the temperature change by  [tex]45^{\circ}[/tex]
