If the number of downloads of the standard version is x, and the high quality is x, 2.1*x+4.1*y=2761 (not 1010 due to that this is multiplied by 2.1 and 4.1, therefore representing the total amount of megabytes) In addition, there are 1010 total downloads, and it's either 2.1 MB or 4.1 MB, so x+y=1010.
We have
2.1x+4.1y=2761
x+y=1010
Multiplying the second equation by -2.1 and adding it to the first equation, we get 2y=2761-1010*2.1=640 and by dividing both sides by 2 we get y=320 downloads of the high quality version

Answer:</h3>
<u>If a rectangle and a triangle have the same area</u>.
Then,
- <u>L × B = 1/2 × B × H</u>
- 10 × 3 = 1/2 × 6 × H
- 30 = 3 × H
- 30/3 = H
- 10 = H
<u>Hence, the height of triangle is 10cm</u>.
