<h3>The answer is:</h3><h2>B</h2><h2 />

First, look for some of the key words in the word problem.

<em>Plus, is the same as the...</em>

Now we can use those key words and translate it into an equation.

You don't know the price of 3 notebooks, so you should put: 3x

Instead of saying plus, we can say: +

It says "...3 notebooks plus a $30 backpack..." so we add 30.

Instead of saying "is the same as the", we can say: =

You don't know the price of 11 notebooks either, so you should put: 11x

Now, put together the equation:

3x + 30 = 11x

There is your equation! Match it up with one of the given answers and you will receive B.

Answer:

\overline {PM} \cong \overline {ON} because they are opposite sides of a parallelogram.

Step-by-step explanation:

First of all, let us have a look at the definition of a parallelogram.

<em>A parallelogram is a closed 4 sided figure (i.e. a quadrilateral) made up with two pairs of straight lines such that the two pairs are parallel and equal to each other.</em>

<em></em>

For example, let us consider a quadrilateral ABCD as attached in the diagram in answer area.

The two pair of lines are:

AB,  DC and BC, AD

For ABCD to be a parallelogram, the lines

AB and DC must be parallel to each other and AB = DC

AND

BC and AD must be parallel to each other and BC = DA

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

In the given question, we are given that the quadrilateral MNOP is a parallelogram.

The two pairs opposite lines are OP, NM and PM, ON.

As per the definition of a parallelogram,

OP and NM must be <em>parallel and equal </em>to each other.

AND

PM and ON must be <em>parallel and equal </em>to each other.

\therefore \overline {PM} \cong \overline {ON}.

Hence proved.
