Answer:
This problem is a great systems of equations problem--you have two different variables: song size and number of songs.
Let's call the number of standard version downloads (S) and the high quality downloads (H).
You can make two statements:
For number of songs downloaded: S + H = 910
For download size: 2.8(S) + 4.4(H) = 3044.
S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:
2.8(S) + 4.4(910 - S) = 3044
2.8S + 4004 - 4.4S = 3044
-1.6S = -960
s = 600
Your question only asks for the standard version downloads, but to help you out in future Systems situations-
You can also solve for H once you have S by plugging it into either of your equations like this:
600 + H = 910
-600
H=310

Remember, volume is length x width x height. (lxwxh)
5+3 inches is the apparent width. (8)
7+7 inches is the height. (14)
The length is seemingly difficult to solve, but it's easy when you get the hang of it.
You need to divide the toolbox into shapes you can find the volume for and then add it all together.
Let's take 14x5x(7+7). 980.
Now the other half. 16x3x(7+7). 672.
Add.
Volume is 1652 inches.

Answer:
x=y=61°
Step-by-step explanation:
x=61°(being the pair of vertically opposite angle)
and,
y=61°(being the pair of corresponding angle)
so, x=y=61°
