Julian has 100 songs on his media player. he knows that 1/4 of the songs are jazz and the rest are pop. which statement correctly describes the songs on julian’s media player?

Julian has 25 Jazz and 75 Pop songs on his media player.

Step-by-step explanation:

100x0.25 + 100x(1-0.25)

Well, I'm guessing this had a multiple choice answer, but we can know that 25 songs are jazz and 75 are pop.

Step-by-step explanation:

To find jazz, we can do 100*1/4, giving us 25, the amount for jazz.

He says that the rest are pop, so therefore 75 are pop.

25% of his songs are jazz and 75% are pop.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
