Data:
Humans (x) = 2 Legs
Horses (y) = 4 Legs
74 Heads
196 Legs
Solving:
Addition method

Simplify by (-4) The first equation







Now, to find the number of horses, I will use the following equation and I will replace the found value, we will have:


Number with incognito are to the left of the equality and numbers without incognito are to the right, remembering that when changing of side changes the signal.


Answer:
Humans = 50Horses = 24
50 = 25 + 0.50w - 0.25w
50 = 25 + 0.25w
50 - 25 = 0.25w
25 = 0.25w
25/0.25 = w
w = 100.
Answer:
50
Step-by-step explanation:
Answer: See below
Explanation:
8x + 14 = 10x - 10 (alt. exterior angle)
8x - 10x = -10 - 14
-2x = -24
x = -24/-2
x = 12
Now plug x = 12 in 10x - 10 to find the angle:
10(12) - 10 = 120 - 10 = 110 degree
Perpendicular has the reciprocal slope and u have to put the point given into point slope.
y-3=9/2(x-4)
(The slope of the original equation was -2/9)
