Question

Alejandro has 3 times as many playlists as Derrick does. Alejandro has 24 playlists. If d = the number of playlists Derrick has, which mathematical sentence expresses the information above?

Answer 1

If Alejandro has 3 times as many playlists as Derrick does, then to get the number of playlists that Alejandro has, we multiply the numbers of playlists Derrick has by 3.

Derrick has d playlists, so the number of playlists Alejandro has is 3 multiplied by d.

The number of playlists Alejandro has = 3 x d

                                                             = 3d


But Alejandro has 24 playlists, so

3d = 24


NOTE:

When we solve this

3d = 24

   d = 8

Derrick has 8 playlists

Answer 2

Answer:

Step-by-step explanation:

If Alejandro has 3 times as many playlists as Derrick does, then to get the number of playlists that Alejandro has, we multiply the numbers of playlists Derrick has by 3.

Derrick has d playlists, so the number of playlists Alejandro has is 3 multiplied by d.

The number of playlists Alejandro has = 3 x d

= 3d

But Alejandro has 24 playlists, so

3d = 24

NOTE:

When we solve this

3d = 24

d = 8

Derrick has 8 playlists
