Janice wants to create a test containing 20 questions worth 50 points. If Janice creates questions worth either two points or fo

Elena L [17]

Answer:

15 two-point questions and 5 four-point questions.

Step-by-step explanation:

Let x represent number of two-points questions and y represent number of four-points questions.

We have been given that Janice wants to create a test containing 20 questions. We can represent this information in an equation as:

$x+y=20...(1)$

Since all questions are worth 50 points. We can represent this information in an equation as:

$2x+4y=50...(2)$

From equation (1), we will get:

$x=20-y$

Upon substituting this value in equation (2), we will get:

$2(20-y)+4y=50$

$40-2y+4y=50$

$40+2y=50$

$40-40+2y=50-40$

$2y=10$

$\frac{2y}{2}=\frac{10}{2}$

$y=5$

Therefore, there are 5 questions that are worth 4 points each.

Now, we will substitute $y=5$ in equation (1) to solve for x.

$x+5=20$

$x+5-5=20-5$

$x=15$

Therefore, there are 15 questions that are worth 2 points each.

Find the real numbers x and y that make the equation true (5-2i)-7=x-(3-yi)

marin [14]

Answer:

x=1 and y=-2

Step-by-step explanation:

5-2i-7=-2-2i

x-(3-yi)=x-3+yi

we write this equation -2 - 2i = (x-3) +yi

so -2=x-3 and -2i=yi

+3 +3 :i :i

1=x -2= y

so x=1 and y= -2
