Answer:
The only algebraic expressions we can find here are the ones for the number of cards that Mr. Bates and Ms. Psenicska have.
We know that Mr. Nates has 3 packs of cards, plus 2 other cards.
If each pack of cards has N cards, then the total number of cards of Mr. Nates is:
Mr. Nates = 3*N + 2
And Ms. Psenicska has 6 packs plus other 8 cards, then she has a total of:
Ms. Psenicska = 6*N + 8
These two are the only expressions we can make with the given information.
So, As Helen divides these pencils, she will divided among, herself, and also her other friends.
This would then signify that the expression would look like the following:

We really do not know how many pencils Helen had, so this is why <em>p </em>is in the equation.
First, let's complete the angles in the triangle. Remember that the sum of the angles in a triangle is 180 degrees.
73 + 90 + x = 180
163 + x = 180
x = 17
So, the angle that completes the triangle is 17 degrees. If we look at that angle in the triangle and the one adjacent to it, we can see that those two angles form a linear pair (or are supplementary, both meaning that they add up to 180 degrees).
17 + x = 180
x = 163
So, 17's supplement is 163 degrees. The 163 degree angle corresponds with angle r, and corresponding angles are congruent.
Therefore, angle r is 163 degrees. The correct answer is option C.
Hope this helps!
