Question

Calcule o valor de x, y e x em 2/3=x/9=8/y=18/z-4

Answer 1

Resposta:

x=6

y=12

z=31

Explicação passo-a-passo:

$\frac{2}{3} = \frac{x}{9}\\ 3x=18\\x=\frac{18}{3} \\x=6\\\\\frac{2}{3}= \frac{8}{y}\\ 2y=24\\y=\frac{24}{2}\\y=12\\\\\frac{2}{3}= \frac{18}{z-4} \\2(z-4)=54\\2z-8=54\\2z=54+8\\z=\frac{62}{2} \\z=31$
