Hello to all friends of the mymathforum 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)

Re: inequality problem and inequalities

multiply by 5







Now just plug in F=-4 and F=23 ( you will get-20C and C=-5C)

Or use the equivalent formula C = 5(F - 32)/9.
