Question

Nas figuras a//b//c, calcule o valor de x​

Answer 1

Resposta:

a x vale 4

b x vale 9

c x vale 2

Explicação passo-a-passo:

Answer 2

A) 2/4 = 3/x

2x = 12

x = 12/2

x = 6

B) 4/12 = x/21

164 = 12x

-12x = -164

x = -164/12

x = -13,6

C) 9/x = 18/4

32 = 18x

-18x = -32

x = -32/18

x= 1,7

D) 8/2x-6 = 12/x-1

8x + 8 = 24x - 72

8x - 24x = - 72 - 8

16x = 80

x = 80/16

x = 5
