Answer 1

Respuesta:

40 years

Explicación paso a paso:

a = d-8

z = 2d

6a = z

a = Anne´s age

d = Daniela´s age

z = Stella´s age

6a = 2d

d = 6a/2 = 3a

a = d-8

a = 3a-8

8 = 3a-a

8 = 2a

8/2 = a

4 = a

6a = z

6×4 = z

24 = z

d = 3*4

d = 12

4 + 24 + 12 = 40

The ages of Anne, Stella and Daniela add up to:

40 years
