Answer:

The number of boys in the school is;

$625$

Explanation:

Given that the ratio of boys to girls in a school is 5:4;

$5\colon4$

And there are 500 girls in the school.

The number of boys in the school will be;

$\begin{gathered} \frac{B}{G}=\frac{5}{4} \\ G=500 \\ B=\frac{5\times G}{4}=\frac{5\times500}{4} \\ B=625 \end{gathered}$

Therefore, the number of boys in the school is;

$625$

Let

x---------> represents Martin's sister's age

y--------> represents Martin's age

we know that

$y=x-6$ --------> equation $1$

$x+y\leq 22$ --------> equation $2$

Substitute equation $1$ in equation $2$

$x+[x-6]\leq 22\\2x\leq 22+6\\ x\leq 14$

therefore

the answer is

Part a) An inequality that can be used to represent this situation is

$x+[x-6]\leq 22$ or $x\leq 14$

Part b) the oldest age Martin's sister can be is $14$ years old
