A test consists of 20questions. Multiple choice questions earn 4points for a correct answer, and free response questions earn 8p
ruslelena [56]

Answer:

15 multiple choice questions

5 free response questions

Step-by-step explanation:

This is basically a systems of equations word problem.

To solve this, we need to create two equations that represent this scenario. Let's suppose m represents the amount of multiple choice questions and f represents the amount of free-choice questions.

We can create the following equations:

4m + 8f = 100

m+f=20

To solve for m and f, we can use elimination.

Let's multiply the equation m+f=20 by -4.

-4m - 4f = -80

Great! Now let's add this equation to our first one, 4m + 8f = 100.

4m + 8f = 100

-4m - 4f = -80

___________________

0m + 4f = 20

4f=20

Dividing both sides by 4 get us f=5.

So there are 5 free choice questions. To find m, we can substitute inside the equation m+f=20

m+5=20\\\\m=20-5\\\\m=15

So there are 15 multiple choice questions.

Hope this helped!

Answer:

A.  6 and 30

B.  8 and 28

Step-by-step explanation:

we know that the area of the three squares must satisfy the Pythagorean Theorem so c² = a² + b²

where

c²  is the area of the largest square

a² and b² are the areas of the smaller squares

now.. 36² = a² + b2

The sum of the areas of the smaller squares must be equal to 36

therefore

6 and 30 >>>> could be the areas of the smaller squares (6 + 30 = 36)

8 and 28 >>>> could be the areas of the smaller squares (8 + 28 = 36)

hope it clears your mind.

Please mark as the brainliest
