Question

100 point test contains a total of 20 questions. The multiple choice questions are worth 3 points each and the short response questions are worth 8 points each.
Write a system of linear equations that represents this situation.

Answer 1

Here's a couple of hints that may help you write this:

1.) You will need two equations
2.) What power is the X in a linear? (For a quadratic, its x^2 and for a cubic, its x^3)
3.) Let X be multiple choice and Y be short response
4.) You were given TWO separate totals since you're writing TWO equations. The totals were 100 and 20

Answer 2

Did you get it @ @chris215

Answer 3

This being Algebra, you'll need to pick some letters to represent quantities. Which quantities are variables and thus representable by letters?

Next, how are those quantities related algebraically?
