Question

calcula "AC". si: BC = 2 AB , CD = 3 BC y AD =54 u

Answer 1

Respuesta:

18u

Explicación paso a paso:

ponemos a AB el valor e x

BC = 2 AB

BC = 2 (x)

BC = 2x

CD = 3 BC

CD = 3 ( 2x)

CD = 6x

ahora sumamos

AB + BC + CD = AD

x + 2x + 6x = 54u

9x = 54u

x = 54u/9

x = 6u

calcula "AC"

AC = AB + BC

AC = x + 2x

AC = 3x

AC = 3(6u)

AC = 18u
