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: D
Step-by-step explanation:
To find the perimeter of the square, you want to first find the length of each side. Since the figure is a square, we know that each side is equal to each other. We can set the expressions equal to each other to find x.
[subtract both sides by 1/2x]
[add both sides by 1]
[multiply both sides by 4]
Now that we know x, we can plug it into each expression to find teh length of each side.
[multiply]
[subtract]
Now that we know each side is equal to 23, we can add all the sides together to find the perimeter.
23+23+23+23=92 or 23×4=92
Since we know that the perimeter is 92 units, the answer is D.
