Question

Encontre o valor de X nas proporções abaixo: 3/x=5/15 6/x=36/6 20/x=5/15 8/x=2/4 x/4=15/2 12/4=x/3

Answer 1

Explicação passo-a-passo:

a)

3/x = 5/15

5x = 3.15

5x = 45

x = 45/5

x = 9

b)

6/x = 36/6

36x = 6.6

36x = 36

x = 36/36

x = 1

c)

20/x = 5/15

5x = 20.15

5x = 300

x = 300/5

x = 60

d)

8/x = 2/4

2x = 8.4

2x = 32

x = 32/2

x = 16

e)

x/4 = 15/2

2x = 4.15

2x = 60

x = 60/2

x = 30

f)

12/4 = x/3

4x = 12.3

4x = 36

x = 36/4

x = 9
