Question

Transforme 30°c e 80°c em Fahrenheit
Formula: c dividido por 5 = f-32 dividido por 9

Answer 1

$\dfrac{C}{5} = \dfrac{F-32}{9} \\\\\\\\ \dfrac{30}{5} = \dfrac{F-32}{9} \\\\\\6= \dfrac{F-32}{9} =\\\\\\\\6 \times 9=F-32\\\\\\54=F-32\\\\F=54+32\\\\F=86$

30° C = 86° F
_____________________________________________________________
$\dfrac{C}{5} = \dfrac{F-32}{9}\\\\\\\\ \dfrac{80}{5} = \dfrac{F-32}{9}\\\\\\16=\dfrac{F-32}{9}\\\\\\\\16 \times 9 = F-32\\\\144=F-32\\\\F=144+32\\\\F=176$

80°C = 176°F
