A quantos graus celsius correspodem 86 graus na escala fahrenheit

Answer 1

A quantos graus celsius correspodem 86 graus na escala fahrenheit

$\dfrac{TC}{5} =\dfrac{TF - 32}{9} \\\\\\ \dfrac{86}{5} =\dfrac{TF - 32}{9} \\\\\\ 17,2\cdot9 = (TF - 32) \\\\\\ 154,8 = (TF - 32) \\\\\\ TF = 154,8 + 32 \\\\\\ TF = 186,8$


Resposta : 186,8 °F

Answer 2

°C/5 = F - 32/9

x/5 = 86 - 32/9

x/5 = 54/9

x/5 = 6

x=6 • 5

x= 30°C
