Question

The number of girls in a classroom is greater than the number of boys. There are more than 2 girls.
Write a system of inequalities to model this situation. Use x to represent the number of boys and y to represent the number of girls.

Answer 1

But which represents both girls and boys

Answer 2

To model the situation described, let's define the variables:

- Let \( x \) be the number of boys.
- Let \( y \) be the number of girls.

From the information given:

1. The number of girls is greater than the number of boys:
\[
y > x
\]

2. There are more than 2 girls:
\[
y > 2
\]

So, the system of inequalities that models this situation is:

\[
\begin{cases}
y > x \\
y > 2
\end{cases}
\]

The inequalities representing the number of boys and girls would be \( y > x \) for comparing boys and girls, and \( y > 2 \) for the condition on the number of girls.

If you are specifically asked to choose which inequality represents the number of girls, it is \( y > 2 \).

Answer 3

The inequality that represents the relationship between the number of boys and girls is:

\[ y > x \]

This means that the number of girls (\(y\)) is greater than the number of boys (\(x\)).

So, in summary:
- \( y > x \) represents the relationship between girls and boys.
- \( y > 2 \) represents the condition that there are more than 2 girls.

Therefore, if you are looking for the inequality that represents both girls and boys, it is \( y > x \).
