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

There are numerous ways to solve this, this is just one of many.
C = 5/9 (F-32) Multiply the equation by 9/5 getting
9/5 C = F-32 Add 32 to both sides of equal sign getting
9/5 C + 32 = F There you are F=9/5 C + 32

Answer 2

Just for fun see what the temperature in fahrenheit (F) is when it is -40 degrees Centigrade.

Answer 3

F =9/5 (-40) + 32
F = -72 +32
F= -40 The one temperature where they read the same.

Answer 4

really? -40 F is the same as -40C?

Answer 5

Yes, the equations show that, and math never lies.

Answer 6

LOL, wow, thats a great fact, i never knew that. thanks! :)

Answer 7

Good luck with your studies, and now you can convert from one system to another.
