Question

A) X/4=y/6=1/2

B) x/15=4/y=2/3​

Answer 1

Resposta:

Explicação passo-a-passo:

a)

$\frac{x}{4}=\frac{y}{6}=\frac{1}{2}\\\frac{x}{4}=\frac{1}{2}\\2x=4\\x=\frac{4}{2}\\x=2\\\frac {y}{6}=\frac{1}{2}\\2y=6\\y=\frac{6}{2}\\y=3$

{x,y}={2,3}

b)

$\frac{x}{15}=\frac{4}{y}=\frac{2}{3} \\\frac{x}{15}=\frac{2}{3}\\3x=30\\x=\frac{30}{3}\\x=10\\\frac{10}{15}=\frac{4}{y}\\10y=60\\y=\frac{60}{10}\\y=6$

{x,y}={10,6}
