Question

Transforma em graus Fahrenheit a) 25°c b) 50°c

Answer 1

Transforma em graus Fahrenheit a) 25°c b) 50°c

A)

$\dfrac{TC}{5}[=\dfrac{TF - 32}{9} \\\\ \dfrac{25}{5} =\dfrac{TF - 32}{9} \\\\ 5\cdot9 = (TF - 32) \\\\ 45 = (TF - 32) \\\\ TF = 45 + 32 \\\\ TF = 77$

B)

$\dfrac{TC}{5} =\dfrac{TF - 32}{9} \\\\ \dfrac{50}{5} =\dfrac{TF - 32}{9} \\\\ 10\cdot9 = (TF - 32) \\\\ 90 = (TF - 32) \\\\ TF = 90 + 32 \\\\ TF = 122$


Resposta :

A) 77 °F
B) 122 °F

Answer 2

25°C

5f-160=9.c

5f-160=225

5f=225+160

5f=385

f=385/5

f=77°


50°


5f-160=9.c

5f=9.(50)+160

5f=450+160

5f=610

f=610/5

f=122°


espero ter ajudado!

boa noite!
