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
Hello,
If 12 balls were pitched to each of the 9 players at practice, then
12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 balls were pitched total.
This is also equal to (12)(9) = 108 balls.
108 balls were pitched during practice.
Hope this helps!
To stretch it vertically, you'll need a coefficient greater than 1 in front of the x. If you want to flip the graph over the x axis that coefficient needs to be negative. So it can only be D

Answer:

Step-by-step explanation:
so first find the common denominator which is 162
so on 4/9 multiply 18 to denominater and numerator which makes it 72/162
next multiply 9 to numerator and denominator in 13/18 which makes it 117/162
so now add:

so now simplification.
189/162 can be reduced by 3
63/54 is our new answer. now we can reduce it by 9
7/6 is our new answer. now we must change it to a mixed number which is 
hope this helped!
