Question

04 Determine o valor de x nas proporções a seguir
a) 2/6 = 9/x
b) 1/3 = y/12
c) z/10 = 6/5
d) 8/t = 2/15​

Answer 1

Resposta:

a) 2/6 = 9/x

2x = 54

x = 54/2

x = 27

b) 1/3 = y/12

12 = 3y

y = 12/3

y = 4

c) z/10 = 6/5

5z = 60

z = 60/5

z = 12

d) 8/t = 2/15​

2t = 120

t = 120/2

t = 60
