Mr. martin’s math test, which is worth 100 points, has 29 problems. each problem is worth either 5 points or 2 points. 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 how many problems of each point value are on the test? 10 problems worth 5 points and 25 problems worth 2 points 14 problems worth 5 points and 15 problems worth 2 points 16 problems worth 5 points and 13 problems worth 2 points 15 problems worth 5 points and 13 problems worth 2 points

Option 2.

Step-by-step explanation:

Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.

Mr. Martin’s math test, which is worth 100 points, has 29 problems.

              .... (1)

        ..... (2)

Multiply equation (1) by 2.

        .... (3)

Subtract equation (3) from equation (2), to eliminate the variable y.

Combined like terms.

Divide both sides by 3.

The value of x is 14.

Substitute x=14 in equation (1).

Subtract 14 from both sides.

The value of y is 15.

It means 14 problems worth 5 points and 15 problems worth 2 points.

Therefore, the correct option is 2.
