Answer 1

Respuesta:

c) solo en III

Explicación paso a paso:

I)

X/10 = (X + 8) / (10 + 1)

X/10 = (X + 8) / 11

11x = 10(x +8)

11x = 10x + 80

X = 80

II)

X/8 = 15/(2+10)

X/8 = 15/12

X/8 = 5/4

X= (5•8)/4

X= 10

III)

X/15 = (X + 8)/(15 + 1O)

X/15 = (x + 8)/25

25x = 15(x + 8)

25x = 15x + 120

10x = 120

x = 120/10

X = 12
