Answer:
20days
Step-by-step explanation:
1 bag feed : 5/2 = 2.5 days
8 bags feed : 2.5*8 = 20 days
The first equation would be 650p+2200s =18150
The second equation would be p + s =16
First, you would find the mean of the data. Once you have the number, you would find the difference between the mean and the other numbers. Once you have all of those numbers, you find the mean of that set. For example:
The mean of this set is 9. We then use this number to find the difference between all of the numbers. So 14-9= 5, 9-7=2, 9-6=3, 9-5=4, 13-9=4. Finding the mean of 5, 2, 3, 4, and 4 results in 18/5 or 3.6
3.6 is the mean absolute deviation.
Assuming 25 and 65 aren't actually supposed to be "25^2" and "65^2"
Answer:
(x-3)
Step-by-step explanation:
2x²+5x-3=x²
+x−6x−3
=x(2x+1)-3(2x+1)
=(2x+1)(x-3)
