Answer:
51 DVDs
Step-by-step explanation:
Let the number of DVDs and CDs sold be x each.
<u>Initial</u>
Number of DVDs= 86
Number of CDs= 52
<u>After selling</u>
Number of DVDs= 86 -x
Number of CDs= 52 -x
Given that there are 3 times as many DVDs than CDs left,
86 -x= 3(52 -x)
<em>Expand:</em>
86 -x= 156 -3x
<em>Bring x terms to 1 side, constant to the other:</em>
3x -x= 156 -86
<em>Simplify:</em>
2x= 70
<em>Divide both sides by 2:</em>
x= 35
Amount of DVDs left
= 86 -x
= 86 -35
= 51
The values of x and y are 2 and 0, respectively
The complete question is given below:-
−−→AB=(xy) a line is given in the question from the image given in the question What values should x and y take?
<h3>How do determine the value of x?</h3>
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
From the graph, we have the following highlights:
Point A is at:
A = 2
The point B is located at:
B = 0
The coordinate (x,y) is represented as:
(x,y) = (A,B)
So, we have:
(x,y) = (2,0)
Hence, the values of x and y are 2 and 0, respectively
