The formula C = 5/9(F32) can be used to convert Fahrenheit temperatures to Celsius temperatures.
a. Gold is liquid for Celsius temperatures C such that 1063 degrees (less than or equal to) C < 2660 degrees. Find a comparable inequality for Fahrenheit temperatures.
b. Silver is liquid for Celsius temperatures C such that 960.8 degrees (less than or equal to) C < 2180 degrees. Find a comparable inequality for Fahrenheit temperatures.
I am not sure how to solve either of these, so please walk me through the process. Thank you!

bobpursley,
I will start you on the second.
find the F that is equivalent t0 960.8, then find F that is equivalent to 2180C
C=5/9(F32)
9/5C=F32
F= 9.5C+32
Put C in, solve for F
