Question

A minha deu 12 °C, quero só confirmar

Answer 1

Resolução da questão, veja:

Converter 10,4 °F para °C:

$\mathsf{\dfrac{\°C}{5}} = \mathsf{\dfrac{\°F-32}{9}}~\to~\mathsf{10,4~\°F}}}\\\\\\\\\ \mathsf{\dfrac{\°C}{5}} = \mathsf{\dfrac{10,4-32}{9}}\\\\\\\\ \mathsf{\dfrac{\°C}{5}} = \mathsf{\dfrac{-21,6}{9}}}\\\\\\\\ \mathsf{9\°C = -108}}\\\\\\\\\\ \mathsf{\°C = \dfrac{-108}{9}}\\\\\\\\\\ \large\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\mathsf{\°C = -12.}}}}}}}}}}}}}}}}}}}}}}$

Ou seja, 10,4 °F equivale a -12 °C.

Espero que te ajude '-'
