Answer:

It will take 100 songs for the monthly price of Napster to cost the same as iTunes.

Step-by-step explanation:

Let's create two equations to represent iTunes (T(d)) and Napster (N(d)):

T(d)=0.99d

N(d)=0.89d+10

In order for us to find when the two prices will be the same, let's set the equations equal to each other and solve for x:

0.99d=0.89d+10

0.1d=10

d=100

the volume of cube A is 216 cubic inches. the length of each edge in cube B is 2 inches longer than the length of each edge in c
Aleonysh [2.5K]
If the side lengths of B are 2x as long as the side lengths of A then the volume of B should be the volume of A^2
216^2=46,656
46,656-216=46,440

This can be more easily displayed with smaller numbers

If cube X were 2*2*2 then the volume would be 8
If cube Y were 4*4*4 then the volume would be 64
8(volume of cube X)^2=64(volume of cube Y)

What property is 4x + 8 = 28
Verdich [7]

Answer:

x=5

Step-by-step explanation:

4x + 8 = 28,

it's rather straight forward,

you would subtract 8 from the left side,

doing the same on the right.

now you have

4x = 20

x= 20/4

x=5

hope this helps.
