use the given formula to convert temperature from Farenheit to Celsius ..then subtract it is easy.
Hello to all friends of the mathhelpforum I'm new in this community. Thank you!
I would like to help me with this exercise, I have to deliver today :
The temperatures in a 24 hour period between -4 ° F and 23 ° F, What was the variation in Celsius? (use F = 9/5 C +32)
First, I'm just going to talk about 1 of them say
You will have to rearrange the equation either before or after you substitute in 23 for F (to make C the subject)
Since you have 2 temperatures to change from Farenheit to Celsius it makes more sense to rearrange the equation to make C the subject first.
F = 9/5 C +32
times both sides by 5 (to get rid of the fraction)
...
5F = 9C+160
Can you do it from here?
Once you make C the subject you can substitute in the 2 values of F (one at a time ) and get the answer that you seek easily.
