Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question.

Let

x------> the number of multiple choice question

y------> the number of free response question

we know that

$3x+8y=55$ -----> equation A

$x+y=15$

$x=15-y$ -----> equation B

Substitute equation B in equation A

$3[15-y]+8y=55$

$45-3y+8y=55$

$5y=55-45$

$5y=10$

$y=2$

Find the value of x

$x=15-y$

$x=15-2=13$

therefore

<u>the answer is</u>

the number of multiple choice question are $13$

the number of free response question are $2$

Answer:

One Solution:

$-3x+y=7\\21x+4y=-8$

Infinitely Many Solution:

$31x-y=4\\61x-2y=8$

No Solution:

$y=-4r+5\\y=-4r+1$

Step-by-step explanation:

System 1

$-3x+y=7\\21x+4y=-8$

$Eq(1)\times7+Eq(2)\\11y=41\\y=\frac{41}{11} \\\\From\ Eq\ 1\\-3x+\frac{41}{11} =7\\-3x=7-\frac{41}{11}\\-3x=\frac{36}{11}\\x=\frac{-12}{11}$

Hence only one solution $(-\frac{12}{11},\frac{41}{11})$

System 2

$31x-y=4\\61x-2y=8$

Both represents the same line. Hence these have infinitely many solutions.

System 3

$y=-4r+5\\y=-4r+1$

Compare both the lines with $y=mx+b$ , where m is the slope.

$m=-4$ for both the lines.

Hence these two lines are parallel that means there does not exists any point of intersection

So this system will not have any solution.
