There are 36 drama DVD's
<em><u>Solution:</u></em>
Given that there are 48 DVD's of comedies and dramas on shelf
25 % of DVD's are comedies
To find: number of drama DVD's
Total number of dvd = 48
Number of comedy dvd = 25 % of 48
Let us find 25 % of 48

Thus, number of comedy dvd = 12
Thus we get,
number of drama DVD's = Total number of dvd - number of comedy dvd
number of drama dvd = 48 - 12 = 36
Thus there are 36 drama dvd's
Answer:


Step-by-step explanation:
Let the quotient be represented by 'Q'.
Given:
The difference of a number 'y' and 16 is 
Quotient is the answer that we get on dividing two terms. Here, the first term is 40 and the second term is
. So, we divide both these terms to get an expression for 'Q'.
The quotient of 40 and
is given as:

Now, we need to find the quotient when
. Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives,

Therefore, the quotient is 10, when the value of 'y' is 20.

Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9
