Using a system of equations, it is found that:
- There are 8 chickens in the yard.
- There are 16 pigs in the yard.
-----------------------------------------
This question is solved using a system of equations. I am going to say that:
- x is the number of chickens.
-----------------------------------------
- A chicken has 1 head, as do a pig.
- There are 24 heads.
Thus:
-----------------------------------------
- A chicken has 2 feet.
- A pig has 4 feet.
- In total, there are 80 feet.
Thus:
-----------------------------------------
Number of chicken:
Since
There are 8 chickens in the yard.
-----------------------------------------
Number of pigs:
There are 16 pigs in the yard.

The first option. If you plug in 2.7 as x the amount would actually be greater than 9 not less.
Ind the area shared by the circles r=2cos(theta) and r=2sin(theta).
<span>i know the general formula for finding the area, but i don't know which is the outside one, and which is the inside circle. but i've tried both ways and am still not getting the right answer. </span>
so let's just say i'll try it with integral .5(4cos(x)^2-.5(4sin(x)^2)
<span>i can factor out a 2, giving me cos(x)^2-sin(x)^2. the integral of that, i believe, can be expressed as 4sin(2x). now i figured the limits of integration were from 0 to pi/4, because those are the two places the circles intersect. so evaluating there, i would get 4-0=4. but I've been told the answer is pi/2 -1. so where am i going wrong, because i'm way off.</span>
Answer:
x = -5/6
Step-by-step explanation:
Multiply both sides by (3x+1):
3x - 2 = 3 (3x + 1)
Distribute:
3x - 2 = 9x + 3
Add 2 to both sides:
3x = 9x + 5
Subtract 9x from both sides:
-6x = 5
Divide both sides by -6:
x = -5/6
