Question

Fahrenheit and Celsius temperatures are related by the formula f = 9/5 c + 32 What is the Celsius temperature if the temperature is -22ºF?
a.
-30ºC
c.
5ºC
b.
-7.6ºC
d.
19ºC

Answer 1

F=(9/5)C +32
F-32 =(9/5) C
(F-32)(5/9)=C

Answer 2

now, F=-22
C= (-22-32)(5/9) =(-54)(5/9)= -30
thus the answer is option a

Answer 3

thank you
