Answer with explanation:</h2>
He has 20 rock songs, 15 country songs, 10 world songs and 5 classical songs.
There are 50 in total.
- The fraction of songs which are rock songs are:
which in simplest fraction is given by:

and on multiplying the fraction with 100 we get the percent of songs.
Hence,

- The fraction of songs which are country songs are:
which in simplest fraction is given by:

Hence,

- The fraction of songs which are world songs are:
which in simplest fraction is given by:

Hence,

- The fraction of songs which are classical songs are:
which in simplest fraction is given by:

Hence,

Answer:
Option 2: (1, 0) and (0, -5)
Step-by-step explanation:
Let's solve this system of equations using the elimination method.
Start by labelling the two equations.
5x -y= 5 -----(1)
5x² -y= 5 -----(2)
(2) -(1):
5x² -y -(5x -y)= 5 -5
Expand:
5x² -y -5x +y= 0
5x² -5x= 0
Factorise:
5x(x -1)= 0
5x= 0 or x -1= 0
x= 0 or x= 1
Now that we have found the x values, we can substitute them into either equations to solve for y.
Substitute into (1):
5(0) -y= 5 or 5(1) -y= 5
0 -y= 5 or -y= 5 -5
y= -5 or -y= 0
y= 0
Thus, the solutions are (0, -5) and (1, 0).
Answer:
25.
Step-by-step explanation:
Looks like you are 25 because the grouping is
4 4 4 4 4 4 1
Six sets of 4 and 1 is left over:- 6 * 4 = 24 and plus 1 gives 25.
