Answer 1

Resposta:

Olá boa tarde!

$\frac{2}{3} =\frac{x}{9} \\\\3x = 18\\\\x = \frac{18}{3} \\\\x= 6\\\\\frac{6}{9}=\frac{8}{y} \\\\6y = 72\\\\y = \frac{72}{6} \\\\y = 12\\\\\frac{8}{12}=\frac{18}{z-4} \\\\8z -32 = 216\\\\8z = 216 + 32\\\\8z = 248\\\\z = \frac{248}{8} \\\\z = 31$

x = 6

y = 12

z = 31
