Answer:
Brody purchased 16 songs.
Step-by-step explanation:
Ratio of the number of songs purchased by Brody(B) and Jayliah(J) = 2 : 3
------(1)
Similarly ratio of the songs purchased by Jayliah(J) and Sadie(S) = 4 : 5
-------(2)
If Sadie bought the songs (S) = 30
From equation (2),

J = 
J = 24
By substituting the value J = 24 in equation (1),

B = 
B = 16
Therefore, number of songs purchased by Brody = 16.
Answer:

Step-by-step explanation:
4x^3-3x^2+x+7 / x-2
2 | 4 -3 1 7
8 22 46
___________
4 11 23 53
This means 4x^2+11x+23 with a remainder of 53
8 times is the correct answer!
so x=5
substituting for x in the equation we get:

Ans C: 16
