Answer:

  300

Step-by-step explanation:

Since nobody failed, the number who passed one or the other was 100%.

  P(O + W) = P(O) +P(W) -P(O&W)

  100% = 80% +70% -P(O&W)

  P(O&W) = 50% = 150 students

If 150 students are 50% of the examinees, then 100% will be 300 students.

A line has a slope of - 4 and includes the points (6,v) and (3,3). What is the value of v?
labwork [276]

Answer:  v = - 9


Step-by-step explanation:

Since two points on the line are given, we use formula for slope.

Let (a,b) and (c,d) be two points on the line, the slope of the line is given by

m=\frac{d-b}{c-a}.

Hence, using this we have

-4=\frac{3-v}{3-6}

Thus, we have

-4×(-3)=3-v⇒12=3-v⇒12-3=-v⇒v=-9

Montano1993 [528]

The books are $5, and the magazines are $10. I’m not sure which way you want it explained but since magazines are twice the price of books, you can solve the equation 3b + 2b = 25. This gives you b=5 which you just multiply by 2 giving you the price of a magazine.
