Question

calcule o valor de x e y
​

Answer 1

Resposta:

Explicação passo-a-passo:

1)

x/6 = 4/8

8.x = 6.4

x = 24/8

x = 3

10/y = 4/8

4.y = 10.8

y = 80/4

y = 20

2)

2.15 = x.3

30/3 = x

x = 10

6.y = 2.15

y = 30/6

y = 5

3)

5/3 = 20/y

5y = 3.20

y = 60/5

y = 12

5/3 = x/6

3.x = 6.5

x = 30/3

x = 10

4)

x.7 = 3.14

x = 42/7

x = 6

2.y = 3.14

y = 42/2

y = 21
