Answer:
idk anyone who could answer else
Step-by-step explanation:
anyone???
Let x = download size of the standard version.
4515 - x = download size of high quality version.
High quality was downloaded 4 times more so 4 x 4.8 = 19.2 = downloads of high quality versions.
Set up a ratio:
2.3 / 19.2 = x / 4515-x
Cross multiply:
2.3(4515-x) = 19.2x
10384.50 -2.3x = 19.2x
Add 2.3x to both sides:
10384.50 = 21.5x
Divide both sides by 21.5:
X = 10384.50/21.5
X = 483
There were 483 downloads of the standard version.
Answer:
The answer should be 8. Hope this help you out.
Let x be the number of rows and y be the number of trees per row.
x* y = 112
and y = 2x - 2
from first equation y = 112/x
so 112/x = 2x - 2
112 = 2x^2 - 2x
2x^2 - 2x - 112 = 0
x^2 - x - 56 = 0
(x - 8)(x + 7) = 0
x = 8 , - 7 (ignore the negative)
so the number of rows = 8
and number of trees per row = 112/8 = 14
Answer number of rows = 8 and number trees i each row = 14.
