Answer:
The answer is (-6).
Step-by-step explanation:
Order the numbers from smallest to largest.
Then start eliminiating one from left, one from right until you get the median. Since in our case the median is in between (-8) and (-4). Sum the numbers and divide them by 2.
Good luck!
There's a relatively easy way to solve problems of this nature. You determine the contribution made if the only contributor is the one that contributes the least.
A chicken has the least number of feet, so 24 chickens will contribute 48 feet.
Now, you consider the change in contribution made by substituting a larger contributor. Each pig that replaces a chicken will add 2 feet to the total.
Consider how many feet need to be added, and thus how many larger contributors are needed. 80 -48 = 32 feet need to be added, so 32/2 = 16 of the animals need to be pigs.
There are 16 pigs and 8 chickens.

Answer:
2.3
Step-by-step explanation:
6.1 =0.8+0.8+x+x
6.1=1.6 +2x
6.1-1.6 = 2x
4.5/2=2x/2
x=2.25
x=2.3
