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

x - the number of 5 points worth problems

y - the number of 2 points worth problems

The test has 29 problems.

Step-by-step explanation:

x - the number of 5 points worth problemsy - the number of 2 points worth problemsThe test has 29 problems.The test is worth 100 points.The system of equations:The solution:There are 14 problems worth 5 points and 15 problems worth 2 points.

x - the number of 5 points worth problems

y - the number of 2 points worth problems

The test has 29 problems. hope this helps

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
