Answer 1

Qual e a temperatura na escala fahreit que um corresponde a 40c

$\dfrac{TC}{5} =\dfrac{TF - 32}{9} \\\\\ \dfrac{40}{5} =\dfrac{TF - 32}{9} \\\\\\ 8\cdot9 = (TF - 32) \\\\\\ 72 = (TF - 32) \\\\\\ 72 + 32 = TF \\\\\\ TF = 72 + 32 \\\\\\ TF = 104$

Resposta : 104 Fahrenheit.

5f-160=9c

5f-160=9.(40)

5f=360+160

5f=520

f=520/5

f=104°f
