46 = n + n + 2 + n + 4 + n + 6
46 = 4n + 12
34 = 4n
n = 8.5
Is it definitely 46?

Add then multiply b through, e to f, hopethsie helps
X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.

So, now that you have y, you can plug it into the first equation to find x:

So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
You would divide it into shapes that you already know, like squares, rectangles and triangles. Find the area of each shape and add them together
