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.
O x + y = 29, 5x + 2y = 100
O x + y = 100, 5x + 2y = 29
5x + y = 29, 2y + x = 100
2x + y = 100, 5y + x = 29
1) Intro
Done

Answer 1

The two equations would be

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

Explanation:

Looking at the points, x and y add up to be 100

x is worth 5 hence 5x and y are worth 2, hence 2y.

there are 29 problems in total. meaning the x + the y add up to 29 problems
