Question

Solving a Real-World Problem

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
O x + y = 29, 5x + 2y = 100
O x + y = 100, 5x + 2y = 29
0 5x + y = 29, 2y + x = 100
O 2x + y = 100, 5y + x = 29

Answer 1

x + y = 29, 5x + 2y = 100

Explanation:

just did it

Answer 2

Answer: From the conditions given, the total number of the problems should be 29. This means that the sum of x and y should be 29. With this and the point-system, the best system of equation that is useful for this problem is,

x + y = 29

5x + 2y = 100

Your first answer choice is the correct answer.

Fact: I suggest looking up the question before asking it because sometimes others have asked the questions and it will be answered. Just letting you know to help you save points.
