There must be fewer than 12 visitors in each tour group.
Black_prince [1.1K]
If there must be LESS than 12 people in the tour group, then it would automatically take out the n>12 because n>12 represents n being MORE than 12, so your answer would be n<12. I hope you aren't totally confused, and good luck on the test!!! I am working on my math skills and I just did this quiz, so the answer is in fact, <. Make me brainliest please, would truly help.

kelly has 4times as many songs on her music playlist as lou . tiffany has 6 times s many songs on her playlist as lou . altogeth
Dmitriy789 [7]
Hello! To answer this question we have to make an equation. In this equation I will represent the total number of songs Lou has as the variable x. 

So 4x +6x + x = 682

This simplifies to 11x = 682. When you divide both sides by 11 you get x = 62.  This is how many songs Lou has. 

Since we are trying to find how many songs Kelly has, we must multiple 62 x 4 to get 248. Kelly has 248 songs.
