$-\cfrac{1}{2}n^2+18=0\implies 18=\cfrac{1}{2}n^2\implies 18=\cfrac{n^2}{2}\implies 36=n^2 \\\\\\ \stackrel{\textit{taking }\sqrt{~~}\textit{ to both sides}}{\pm\sqrt{36}=\sqrt{n^2}}\implies \pm 6 = n$

Joe’s age is three times Aaron’s age and Aaron is six years older than Christina. If the sum of their ages is 149, what is Chris

Leno4ka [110]

<u>Answer</u>

If Christina's age is = x

Aaron's age is = x + 6

Jeo's age = 3(x + 6 )

So, the sum of their ages can be write as,

$x + x + 6 + 3(x + 6) \\ x + x + 6 + 3x + 18 \\ 5x + 24$

Also, they have given that the sum of their ages is 149

Therefore we can write a equation as,

$5x + 24 = 149$

Now let's solve this and find the age of Christina

$5x + 24 = 149 \\ 5x = 149 - 24 \\ 5x =12 5 \\ \frac{5x}{5} = \frac{125}{5} \\ x = 25$

Aaron's age is

$x+ 6 \\ 25 + 6 \\ = 31$

Joe's age is

$3(x + 6) \\ 3(25 + 6) \\ 3 \times 31 \\ = 93$

Hope this helps you.
