Por favor ajudem.

Answer 1

Resposta:

A) X = 6  B) X = 15  C) X = 10  D) X = 16

Explicação passo-a-passo:

A) X/4 = 30/20

X.20 = 30.4

20X = 120

X = 120/20

X = 6

B) X.4 = 2.30

4X = 60

X = 60/4

X = 15

C) 15.X = 6.25

15X = 150

X = 150/15

X = 10

D) X.70 = 80.14

70X = 1120

X = 1120/70

X = 16

Answer 2

Resposta:

A) X/4 = 30/20
