Question

calcule o valor dos termos desconhecidos ​

Answer 1

a) x = 6,6

b) x = 6

c) x = 1/4

a) 15/5 = 20/x

15x = 5.20

15x = 100

x = 100/15

x = 6,6

b) x/2 = 3/1

x = 2.3

x = 6

c) 4x+1/x+2 = 16/18

18(4x+1) = 16(x+2)

72x+18 = 16x+32

72x-16x = 32-18

56x = 14

x = 14/56 simplificando 1/4
