Please teach me the steps on how to do it I`m having trouble on these problems in homework and school. Thank you!
248
Kelly has 248 songs
Lou = L
Kelly = 4L
Tiffany = 6L
L + 4L + 6L = 682
11L = 682
L = 62
BTW, kelly has 248 songs
To solve this problem, you can set up a system of equations representing the given information. Let's assume that Lou has x songs on his music player.
According to the problem, Kelly has 4 times as many songs as Lou. Therefore, Kelly has 4x songs on her music player.
Tiffany has 6 times as many songs as Lou, which means Tiffany has 6x songs on her music player.
The sum of their songs is 682, so the equation becomes x + 4x + 6x = 682.
Combine like terms on the left side of the equation: 11x = 682.
Now, solve for x by dividing both sides of the equation by 11: x = 62.
This tells us that Lou has 62 songs on his music player.
To find the number of songs Kelly has, substitute the value of x back into the equation for Kelly's songs: 4x = 4 * 62 = 248.
Therefore, Kelly has 248 songs on her music player.
To summarize:
Lou has 62 songs.
Kelly has 248 songs.
Tiffany has 6 times as many songs as Lou, which is equal to 6 * 62 = 372 songs.
