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

Answer 1

A

Explanation:

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

Answer 2

Answer:the first choice

Explanation:

The test has 29 problems. That means x problems + y problems =29

The x problems are worth 5 points. So that’s 5x. The y problems are worth 2 points. So that’s 2y. The total the points add up to is 100. So 5x+2y=100

The first answer choice shows that
