Question

converta as seguintes temperaturas abaixo 15c em fahrenheit

Answer 1

F-32/9 = C/5
F-32/9 = 15/3

F-32 = 3 * 9
F = 27 + 32
F = 59

Answer 2

Olá !

Resolução :

$\mathsf{\dfrac{TC}{5} =\dfrac{(TF - 32)}{9}} \\\\\\ \mathsf{\dfrac{15}{5} =\dfrac{(TF - 32)}{9}} \\\\\\ \mathsf{ 3 =\dfrac{(TF - 32)}{9}} \\\\\\ \mathsf{\dfrac{3}{1} =\dfrac{(TF - 32)}{9}} \\\\\\ \mathsf{ (TF - 32) = 9\cdot3} \\\\\\ \mathsf{ (TF - 32) = 27 } \\\\\\ \mathsf{ TF = 27 + 32 } \\\\\\ \mathsf{ TF = 59}$

RESPOSTA : 59 °F
