The equation [tex]F = 1.8C + 32[/tex] can be used to convert from Celsius to Fahrenheit, where [tex]C[/tex] is the temperature in degrees Celsius and [tex]F[/tex] is the temperature in degrees Fahrenheit.

If the temperature is 20 degrees Celsius, find the temperature in degrees Fahrenheit.

Answer :

To convert from Celsius to Fahrenheit, we use the formula

[tex]$$
F = 1.8C + 32.
$$[/tex]

Given that the Celsius temperature is [tex]$C = 20$[/tex], we substitute this into the formula:

[tex]$$
F = 1.8 \times 20 + 32.
$$[/tex]

First, we calculate the multiplication:

[tex]$$
1.8 \times 20 = 36.
$$[/tex]

Then, we add the constant [tex]$32$[/tex]:

[tex]$$
36 + 32 = 68.
$$[/tex]

Thus, the temperature in degrees Fahrenheit is [tex]$\boxed{68}$[/tex].
