Question

Formula : Tc. = Tf – 32 = Tk – 273 5 9 5
1) Transformar 86ºF em graus Celsius.

2) Transformar 54ºC em Fahrenheit.

3) Transformar 124 k em graus Fahrenheit.​

Answer 1

Resposta:

$1) \frac{c}{5} = \frac{86 - 32}{9} \\ 9c = 5 \times (86 - 32) \\ 9c = 5 \times 54 \\ c = \frac{270}{9} = 30 \\ \\ 2) \frac{54}{5} = \frac{f - 32}{9} \\ 5 \times (f - 32) = 54 \times 9 \\ 5f - 160 = 486 \\ 5f = 486 - 160 \\ f = \frac{326}{5} = 65.2 \\ \\ 3) \frac{124 - 273}{5} = \frac{f - 32}{5} \\ f - 32 = 124 - 273 \\ f = - 149 + 32 \\ f = - 117$
