The temperature in degrees Celsius can be expressed by the function c(f)=5/9(f-32) where f is the temperature in degrees farenheit. Find the temperature in degrees Celsius (to the nearest degree) if it is 7 degrees farenheit

Respuesta :

5/9(7-32)
-125/9
-13.88888
7 -32= -25 
-25 x 5 = -125
-125 / 9 ≈ -13.8
