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

SpyIntel [72]

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:

x = 30

Step-by-step explanation:

$\frac{3}{5}$ (30) + $\frac{1}{3}$ (30) = 28

$\frac{3}{5}$ (30) = 18

$\frac{1}{3}$ (30) = 10

18 + 10 = 28
