Question

The formula for degrees Celsius is: C =5/9(F − 32), where F stands for degrees Fahrenheit.

Part 1: Solve the equation for F and show all steps.
Part 2: Determine how many degrees Fahrenheit 20 degrees Celsius is.

Answer 1

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

Answer 2

5/9(20-32)
5/9*12
5/108

Answer 3

im still confused.
can you decribe the steps as you go please?

Answer 4

\[F=(9/5)C+32=1.8C+32\]
1.8 x (20 Celsius)+32=68 Farenheit

Answer 5

Look, you want to find \(F\) from the equation \(C=\frac59(F-32)\).
1 step:
Multiplying both parts of the equation on \(\frac95\):
\[\frac95C=\frac95\cdot\frac59(F-32)\]We have that \(\frac95\cdot\frac59=1\). So, we have
\[\frac95C=1\cdot(F-32)\]\[\frac95C=F-32\]2 step:
Adding 32 to both parts of the equation:
\[\frac95C+32=F-32+32\]We have that \(-32+32=0\). So, we have
\[\frac95C+32=F+0\]\[\frac95C+32=F\]Or \(F=\frac95C+32\).
