Question

Expresse essa temperatura na escala Celsius 68f

Answer 1

Expresse essa temperatura na escala Celsius 68f

$\dfrac{TC}{5} =\dfrac{TF - 32}{9} \\\\\\ \dfrac{TC}{5} =\dfrac{68 - 32}{9} \\\\\\ \dfrac{TC}{5} =\dfrac{36}{9} \\\\\\ 9TC = 5\cdot36 \\\\\\ 9TC = 180 \\\\\\ TC =\dfrac{180}{9} \\\\\\ TC = 20$


Resposta : 20 °C

Answer 2

Oi Bom dia


Formula de conversão de fahrenheit para celsius ou de celsius para fahrenheit :


TC/5 = TF - 32/9


TC/5 = 68 - 32/9
TC/5 = 36/9
TC/5 = 4
TC= 4 × 5
TC= 20 ° C


Resposta = 20° C


Bons estudos :)
