Since you want your answers in Celsius, we have to convert our formula
F=9/5C+32
F - 32 = (9/5)C
(5/9)(F - 32) = C
I will do b), you do the rest
when F = 68, C = (5/9)(68-32) = 20° C
when F = 86, C = (5/9)(86-32) = 30° C
Each of the following temperature ranges is in degrees Fahrenheit. Use the formulaF=9/5C+32 to find the corresponding temperature range in degrees Celsius (using interval notation and assume inclusion).
a.23∘ to 50 ∘
b.68∘ to 86∘
c. -4∘ to 14∘
d. 104∘ to 140∘
