Question

Converte 200 K em °F

Answer 1

F - 32 / 9 = K - 273 / 5

F - 32 / 9 = 200 - 273 / 5

5 * (F - 32) = 9 * (200- 273)

5F - 160 = 9 * (-73)

5F = -657 + 160

5F = -497

F = -497 / 5

F = - 99,4

Answer 2

Usamos a seguinte relação:

$\mathsf{ \frac{TF-32}{9} = \frac{Tk-273}{5}} \\ \\ \mathsf{5(TF-32)=9(Tk-273)} \\ \\ \mathsf{5TF-160=9Tk-2457} \\ \\ \mathsf{5TF+2297=9Tk} \\ \\ \mathsf{5TF=9*200-2297} \\ \\ \mathsf{5TF=1800-2297} \\ \\ \mathsf{5TF=-497} \\ \\ \boxed{\boxed{\mathbf{TF=-99,4}}}~\checkmark$
