Question

Tim says -40°f is equal to -40°c. explain why this is true.

Answer 1

`^(\circ)C=(^(\circ)F-32)\cdot(5)/(9)\\\\ ^(\circ)C=(-40-32)\cdot(5)/(9)\\ ^(\circ)C=-72\cdot(5)/(9)\\ ^(\circ)C=-8\cdot5\\ ^(\circ)C=-40`

Answer 2

Let C = degrees Celsius and F = degrees Fahrenheit
`C = (F - 32) * (5)/(9)\\\\`
`= (-40 - 32) * (5)/(9)\\\\`
`= (-72) * (5)/(9)\\\\`
`= -(360)/(9) \\\\`
`= -40`
