Question

a) Transforme 30°C (graus Célsius) em °F (Fahrenheit)

b) Transforme 50°F em °C

Answer 1

Olá, utilizarei a fórmula:

$\frac{Tc}{5}=\frac{Tf-32}{9}$

Ficando da seguinte forma:

a)$\frac{30}{5}=\frac{Tf-32}{9} \\ 6=\frac{Tf-32}{9} \\ Tf-32=9.6\\Tf-32=54\\Tf=54+32 \\Tf=86$

Resposta a): 86°F

b)$\frac{Tc}{5}=\frac{50-32}{9} \\ \frac{Tc}{5} =\frac{18}{9}\\ \frac{Tc}{5}=2\\Tc=5.2\\ Tc=10$

Resposta b): 10°C

Answer 2

Fórmula = °C/5 = °F - 32/9

$a) \frac{ 30}{5} = \frac{f - 32}{9} \\ 5(f - 32) = 30 \times 9 \\ 5f - 160 = 270 \\ 5f = 270 + 160 \\ 5f = 430 \\ f = \frac{430}{5} \\ f = 86 \\ \\ b) \frac{c}{5} = \frac{50 - 32}{9} \\ c \times 9 = 5(50 - 32) \\ 9c = 250 - 160 \\ 9c = 90 \\ c = \frac{90}{9} \\ c = 10$
