Question

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

Answer 1

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

Explanation:

Since x is the number of questions worth 5 points and y is the number of questions worth 2 points.

The total problem: x + y = 29

The total points: 5x + 2y = 100

Answer 2

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

Explanation:
