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 25 degrees Celsius is.

Answer 1

so just rearrange this so f = something

C = 5/9(F-32)

first multiply both sides by 9/5 (the reciprocal o 5/9 thus canceling this out)

9/5C = F - 32

add 32 to both sides to make F be alone

F = 9/5C + 32

if this is true...then

Part 2: Determine how many degrees Fahrenheit 25 degrees Celsius is.

we take our equation

F = 9/5C + 32

and plug in 25 for C

so

F = 9/5(25) + 32
F = 225/5 + 32
F = 45 + 32
F = 77
