Question

A tennis team has 24 members. There are twice as many girls as boys on the team. How many girls are on the tennis team? 6 girls 8 girls 12 girls 16 girls

Answer 1

There are 16 girls.

Answer 2

16 Girls

Explanation:

Let x be the number of boys.

Let y be the number of girls.

So we know that:

y = 2x

y + x = 24

We can get the answer through substitution. Since we know that y = 2x, we can insert that into our second equation by replacing the y with the equation we came up with for y in the first equation.

`y + x = 24`

`2x + x =24`

`3x =24`

`x =(24)/(3)`

`x =8`

With that, we insert that answer into our first equation:

y =2x

y = 2(8)

y = 16

So there are 16 girls.
