Atest is worth 100 points. the test is made up of 40 items. each item is worth either 2 points or 3 points. which matrix equation and solution represent the situation?

c on edg.

Step-by-step explanation:

Total number of points in the test = 100

Total number of items in the test = 40

Let number of items of 2 points be x and number of items of 3 points be y.

Now, using the given information the situation can be represented by using the following equations :

⇒ x + y = 40 .........(1)

⇒ 2x + 3y = 100 .........(2)

The matrix equation is :

By solving the equation (1) and equation (2), we get :

Solution : x = 20 and y = 20

step-by-step explanation:

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
