Question

9) Nas figuras , a//b//c , calcule x:
​

Answer 1

Resposta:

a)

$\frac{2}{4} = \frac{3}{x}$

2x = 12

$x = \frac{12}{2} = 6$

b)

$\frac{3}{x} = \frac{6}{4}$

6x = 12

$x = \frac{12}{6} = 2$

$\frac{10}{3} = \frac{y}{6}$

3y = 60

$y = \frac{60}{3} = 20$

Answer 2

Resposta:

a) x=6

b) y=20; X=2

Explicação passo-a-passo:

1) 2/4=3/x

X*2/3=4

X*2=4*3

X=12/2

X=6

2)

10/y=3/6

Y*3/6=10

Y*3=10*6

y=60/3

y=20

3/6=X/4

3/6*4=X

12/6=X

2=X
