Answer:
Step-by-step explanation:
either cow or pigs
Either pigs or cow = 40
(1) Let number of pigs be x
then number of cows >twice of pigs = 2x
number of pigs + number of cows = 40
number of cows = 40 -x
40-x > 2x
40 > 3x
x < 
x < 12.33
nearest integral number is 12
so its 12
so number of pigs will be 12 so that number of cows = 40 -12 = 28
which is more than twice of number of pigs
28 > 2( 12) = 24
(2) number of pigs + number of cows = 40
for x>12
number of cows = 40 -x
x > 12
-x < -12
adding 40 both sides
40-x < 40-12
number of cows <28
Answer:
x = 8
Step-by-step explanation:
I am assuming that you want to solve for x.
Note the equal sign, what you do to one side, you do to the opposite side. Isolate the variable, x. Add 2 to both sides:
x - 2 (+2) = 6 (+2)
x = 6 + 2
x = 8
x = 8 is your answer.

Answer
B
Explanation
Look for a 9 on the y axis then do Y2-Y1/X2-X1 with any 2 plots on the table
Pick any value in the y column of the table. I'm going to pick 81. Divide the value you picked by the previous y value, which in my case would be 9
Dividing the values gives: 81/9 = 9
So the base is 9. We multiply each y value by 9 to get the next y value
Eg: to go from 1/81 to 1/9, we multiply by 9. Same for 1/9 to 1, and so on.
Answer: Choice B) 9
Note: This trick only works because x is increasing by 1 each time
