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:
Its 52/69... did u mean 69 divide by 52? If so the answer is 69/52.

Hopefully u wrote the answer correctly, as always plz mark as brainliest. Hope this helps!
Oh wait!
The decimal form is: 0.753621 i think
Answer:
Check the attached document for the solutions, cheers
Step-by-step explanation:
<span>To do that, you need to set it all to zero and factor:
x^2+8x+15 = 0
(x+5)(x+3) = 0
then put both those in parentheses chunks in their own equations
x + 5 = 0
x + 3 = 0
and then simplify
x = -5
x = -3
So the two points where the parabola crosses the x-axis are -5 and -3.</span>
Answer:3,600
Step-by-step explanation:
Find the Prime factorization of 400: 2x2x2x2x5x5
Find the Prime factorization of 900: 2x2x3x3x5x5
Multiply each factor the greater number of times it occurs: 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5= 3,600
