Answer
1)Linear equation : F = C*1.8 +32.
2) Value for 72 F to Celsius from above equation is:
C = 22.222 Celsius
Work Step by Step
relation between Celsius (C) and Fahrenheit (F):
1) 0 Celsius = 32 F and,
2) 100 Celsius = 212 F
So, from above give information we can conclude that
F = C + 32
but this relation only holds for 0 Celsius. So, for values more than 0 there should some multiplying factor to C. i.e
F = C*x +32
We can calculate value of x by substituting values for 100 Celsius in above equation:
212 = 100*x +32
x = 1.8
Now putting this value in above equation:
F = C*1.8 +32
To convert 72 F in to Celsius:
72 = C*1.8 +32
C = 22.222 Celsius
