Question

Transforme ou converta -15°k em °F (Ciências)

Answer 1

Olá !

Transformando -15 K em °F.

$\mathsf{\dfrac{(T_{K} - 273)}{5}=\dfrac{(T_{F} - 32)}{9}} \\\\\\ \mathsf{\dfrac{(-15 - 273)}{5}=\dfrac{(T_{F} - 32)}{9}} \\\\\\ \mathsf{9(-15 -273) = 5(T_{F} - 32)} \\\\\\ \mathsf{-135 - 2457 = 5T_{F} - 160} \\\\\\ \mathsf{-2592=5T_{F} - 160} \\\\\\ \mathsf{5T_{F} - 160 = -2592} \\\\\\ \mathsf{5T_{F} = -2592 + 160} \\\\\\ \mathsf{5T_{F} = -2432} \\\\\\ \mathsf{T_{F}=\dfrac{(-2432)}{5}} \\\\\\ \mathsf{\boxed{T_{F}=-486,4}}$

$\textbf{RESPOSTA~~:}$ -486,4 °F
