Answer:
Step-by-step explanation:
In this question we have to find the expression for the value of temperature in terms of degrees Celsius.
Since, the given expression is,
F = 1.8C + 32
F - 32 = 1.8C + 32 - 32
F - 32 = 1.8C
[tex]\frac{F-32}{1.8}=\frac{1.8C}{1.8}[/tex]
[tex]\frac{F-32}{1.8}=C[/tex]
For F = C,
[tex]\frac{C-32}{1.8}=C[/tex]
C - 32 = 1.8C
C - 1.8C = 32
-0.8C = 32
C = [tex]-\frac{32}{0.8}[/tex]
C = -40
Therefore, at (-40°C) degrees of temperature degrees Fahrenheit and degrees Celsius are equal.
