5. Zoe and Claire are sisters. They are giving clues about their heights. Write an equation and
solve to determine the height of both Zoe and Claire.
#1: Claire is twice as tall as Zoe.
#2: Together, Claire and Zoe are
108 inches tall

Respuesta :

Using a system of equations, it is found that:

  • Zoe is 36 inches tall.
  • Claire is 72 inches tall.

------------------------

  • The heights are unknown, so we are going to call it x and y.
  • x for Claire, y for Zoe.
  • Claire is twice as tall as Zoe, thus [tex]x = 2y[/tex]
  • Together, they are 108 inches tall, thus:

[tex]x + y = 108[/tex]

Since [tex]x = 2y[/tex]

[tex]2y + y = 108[/tex]

[tex]3y = 108[/tex]

[tex]y = \frac{108}{3}[/tex]

[tex]y = 36[/tex]

[tex]x = 2y = 2(36) = 72[/tex]

Zoe is 36 inches tall.

Claire is 72 inches tall.
