Answer:

13 cows, 12 chickens

Step-by-step explanation:

Total number of animals= 25

Total number of legs= 76

Let the number of cows be x and the number of chickens be y.

x +y= 25 -----(1)

Since each cow has 4 legs and each chicken has 2 legs,

4x +2y= 76 -----(2)

The second equation can be simplified by dividing both sides of the equation by 2:

2x +y= 38 -----(3)

Let's solve by elimination!

(3) -(1):

2x +y -(x +y)= 38 -25

Expand:

2x +y -x -y= 13

x= 13

Substitute x= 13 into (1):

13 +y= 25

y= 25 -13

y= 12

-8x^2+4x+5=0 using quadratic formula
daser333 [38]
So you want to solve for x?

It would be nice if this would easily factor:
(-4x + 5)(2x +1)  = 0    This will not work!

So you need to use the quadratic formula:
a = -8, b = 4, c = 5

x = \frac{-b+/-  \sqrt{b^{2}-4ac} }{2a}

x = (-4 +/- \sqrt{16-4(-8)(5)})/2(-8)
   = (-4 +/- \sqrt{16 + 160})/-16
   = (-4 +\sqrt{176})/-16
   = 1/4 - \sqrt{11}/4
