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 .
x =62.
How many songs Kelly has = 4x = 4*62 = 248 songs.
<span>Kelly = 248 songs.</span>
Answer:
-15
Step-by-step explanation:
Isolate x to solve
-9=6+x
-6 -6
-15=x
1/2(5 sqrt 2)(4 sqrt 2)= 20
Answer:
2
Step-by-step explanation:
Basically you don't need to find x to know the scale factor ,
but I did.So you see that multiple 3 by 2 you will get 6
(MN) and the same will happen with 5.5 and NO (which is 11 btw).
so you can write 2:1
