E = mgh
m = E/gh
g = E/mh
h = E/mg
Horse = x = 1 head and 4 feet
Chicken =y = 1 head and 2 feet
Horse + chicken = x + y = 43 ( total heads)
Horse = 43 - y
4x + 2y = 122
4(43-y) + 2y = 122
Simplify:
172-4y + 2y = 122
Combine like terms
172-2y = 122
Subtract 172 from both sides
-2y = -50
Divide both sides by-2
Y = 25
X + y = 43
X + 25 = 43
X = 18
There are 18 horses and 25 chickens.
Slope: M = rise/run = y2 - y1/x2 - x1
Point slope: y-y₁=m(x-x₁)
Slope-intercept: y = mx+b
if u calculate 3 1/4 u would get 13/4
This means to get the reciprocal fraction of 13/4 just turn it upside down like this
13/4= 4/13 so ur answer is 4/13
