A Web music store offers two versions of a popular song. The size of the standard version is 2.3 megabytes (MB). The size of the high-quality version is 4.2 MB. Yesterday, there were 990 downloads of the song, for a total download size of 3427 MB. How many downloads of the standard version were there?

Step-by-step explanation:

If there was 3427 MB, the lower quality would've gotten 1,490 sales alone.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

ok then what happened.
