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
1) --
2) --
3) 175,900 / 12.5% = 1,407,200 CHOICE B.
4) SUPPLIES
5) PURCHASES
6) 5,000 + 21,800 - 790 - 5,100 = 20,910 CHOICE D.
7) D. 50%
8) C. UNITS OF PRODUCTION
9) B. INCOME STATEMENT
10) A.) 6,480
11) D.) MULTIPLIED BY BOOK VALUE AT THE BEGINNING OF THE YEAR.
Lets take it in order:
1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5
Check my math, as I just did it in my head
