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:
one solution with a y value of 5
Step-by-step explanation:
/| x+y-4 = 0| x-y-6 = 0
We try to solve the equation: x+y-4 = 0
x+y-4 = 0 // - x-4
y = -(x-4)
y = 4-x
We insert the solution into one of the initial equations of our system of equations
We get a system of equations:
/| x+x-6-4 = 0| y = 4-x
2*x-10 = 0 // + 10
2*x = 10 // : 2
x = 10/2
x = 5
We insert the solution into one of the initial equations of our system of equations
For y = 4-x:
y = 4-5
y = -1
We get a system of equations:
/| y = -1| x = 5
