Answer:
540 megabytes
Step-by-step explanation:
We will first need to find out how much space a<em> singular song</em> will take up. We will do this by <em>the storage taken up (884) by the number of songs she has:</em>
884 / 221 = 4 mb taken up per song
Then we want to find out how many megabytes <em>135 of these songs take up</em>, so we will multiply the <em>mb taken up per song (4) by the number of songs we want to find (135)</em>:
4 x 135 = <em>540 megabytes</em>

Answer:
EG = 19
Explanation:
Given that a line segment CD. EF bisects the line CD at point G.
Length of CG = 5x-1
Length of GD = 7x - 13
We know that CG = GD
5x-1 = 7x-13
Solve for x,
2x = 12
x = 6
Now given that,
EF = 6x-4
GF = 13
EF = EG + GF
6x - 4 = EG + 13
EG = 6x - 4 - 13
EG = 6x - 17
put the value of x = 6, in order to find the EG
EG = 6*6 - 17
EG = 19
That's the final answer.
I hope it will help you.
Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
