Question

The formula to convert Fahrenheit to Celsius is C = 5/9 (F-32). convert 12C to Fahrenheit . Round to nearest degree.

Answer 1

The formula to convert Fahrenheit to Celsius is C = 5/9 (F-32).

convert 12C to Fahrenheit

We replace 12 with C in the formula

`12 = (5)/(9) (F-32)`

Now multiply the fraction inside the parenthesis

`12 = (5)/(9)F-(5)/(9)*32`

`12 = (5)/(9)F-(160)/(9)`

Add the fraction on both side

`12+(160)/(9) = (5)/(9)F`

`(108+160)/(9) = (5)/(9)F`

`(268)/(9) = (5)/(9)F`

multiply by 9/5 on both sides

`(268)/(9) *(9)/(5) = F`

`(268)/(5) = F`

F= 53.6

So Fahrenheit = 53.6

When we round to nearest degree it becomes 54
