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

the answer is

the number of multiple choice question are $13$

the number of free response question are $2$

Answer:

Step-by-step explanation:

TO PROVE : Δ NLM $\sim$ ΔELF

i) ∠NLM = ∠ELF ( Common angle )

ii) $\frac{LN}{LE} = \frac{LM}{LF} = \frac{40}{16} = \frac{45}{18} =\frac{5}{2}$ (∴ EF ║ NM )

iii) ∠LNM = ∠LEF ( ∵ EF ║ NM & corresponding angle )
