Answer 1

Resposta:

a. x = 9  b. x = 6  c. x = 1  d. x = 16

Explicação passo a passo:

$a) \frac{3}{6}=\frac{x}{18} \\6x = 54\\x = \frac{54}{6} \\x=9$  

 $b) \frac{14}{x}=\frac{28}{12} \\28x = 168\\x= \frac{168}{28} \\x=6$  

 $c) \frac{8}{48}= \frac{x}{6}\\48x =48\\x=\frac{48}{48}\\x=1$    

$d) \frac{18}{48}=\frac{6}{x} \\18x = 288\\x= \frac{288}{18} \\x=16$
