Question

Como transformá 20°C em grau fahrenheit

Answer 1

Olá !


Resolução :

$\dfrac{TC}{5} =\dfrac{TF - 32}{9} \\\\\\ \dfrac{20}{5} =\dfrac{TF - 32}{9} \\\\\\ 4 =\dfrac{TF - 32}{9} \\\\\\ (TF - 32) = 9\cdot4 \\\\\\(TF - 32) = 36 \\\\\\ TF = 32 + 36 \\\\\\ TF = 68$


Resposta : 68 °F

Answer 2

Bom Dia!

TC = TF-32

 5          9

20 = TF-32

 5         9

4 = TF-32

1        9

36 = TF-32

-TF = -32-36

-TF = -68 (-1)

T = 68°F
