Question

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

Part 1: Solve the formula for F. Show all steps.
Part 2: Determine how many degrees Fahrenheit 4 degrees Celsius is.

Answer 1

formula for f
multiply by 5(F-32)
divide by 5C
add 32

Answer 2

plug 4 into the original equation

Answer 3

what?

Answer 4

That's wrong :( hold on... :(

Answer 5

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

So solve for F by first multiplying both side by (9/5):

(9/5)C = (9/5)(5/9)(F-32)
(9/5)C = F - 32
Then add 32 to both sides:

(9/5)C + 32 = F

So: F = (9/5)C + 32
