Answer:
The answer is given below.
Step-by-step explanation:
Alternate exterior angles: I is a pair of angles on the outer side of the each of two parallel lines but on opposite side of the transversal.
Vertically opposite angles: They are angles opposite each other when two lines intersect each other or cross each other.
Corresponding angles: The angles which occupy the same relative position at each intersection where a transversal intersect the two parallel lines.
Same side interior angles: These are the angles between the parallel lines with the transversal.
Alternate interior angles: These are those angles that are alternate to each other and lie inside the parallel lines forming in Z shape.
Linear pair angles: It is a pair of adjacent angles formed by two intersecting lines
The numbers of new CDs is 30 and the old CDs is 21.
To solve this problem, we have to write a system of equations in which we would know the numbers of each types of CD she bought.
<h3>System of Equations</h3>This is used to solve a series or complex of word problems in which we can represent in a mathematical statements;
- Let n represents numbers of new CDs
- Let u represents numbers of old CDs
The equations can be represented as
Let's take equation (i)
Making n the subject of formula
we can put equation (iii) into equation (ii)
Let's put the value of u into equation (i)
From the calculations above, the numbers of new CDs is 30 and the old CDs is 21.
