Answer:
the answer is D
how to try the values of the x and y
(x,y)
<span>670,200,000 in scientific notation
=
6.702 x 10^8</span>
Let the number of songs owned by Lou be = x.
Kelly has 4 times as many songs as Lou = 4x
Tiffany has 6 times as many songs as Lou = 6x
They all have total of 682 songs
= x + 4x + 6x = 682
11x = 682
x = 682 / 11 . Use your calculator.
x =62.
How many songs Kelly has = 4x = 4*62 = 248 songs.
Kelly = 248 songs.
