Question

According to Teo's bread recipe, he should bake the bread at ° for 30 minutes. His oven measures temperature in °F. To what temperature, in °, should he set his oven? Rewrite the formula C= 59 F-32 to find the Fahrenheit temperature that is equal to °C.

Answer 1

`F = (9)/(5)(C + 32)`

Explanation:

Given

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

First, we need to solve for F

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

Add 32 to both sides

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

`C + 32 = (5)/(9)F`

Multiply both sides by
`(9)/(5)`

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

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

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

`F = (9)/(5)(C + 32)`

Next, is to determine the temperature in degrees Fahrenheit

However, this is not stated the degree Celsius equivalent is not stated in your question.

So, I'll assume a value for it.

Assume that C = 23

Substitute 23 for C in
`F = (9)/(5)(C + 32)`

`F = (9)/(5)(23+ 32)`

`F = (9)/(5)(55}`

`F = 9 * 11`

`F = 99`
