Answer:
only keeps-
cows=134-67-34-10=23
sheep=142-67-34-15=26
goats=76-10-34-15=17
no pets=205-23-17-26-67-10-16-34
Step-by-step explanation:
some have one pets some have two or three
total no. of family have cows is 134 then 134 minus by those with more will be no. of family only with cows
Answer:
2x=-1 or x=-0.5
Step-by-step explanation:
4x-6=10x-3 (-4x)
-6=6x-3 (+3)
-3=6x (divide by 3)
-1=2x

Answer: 10 feet</h3>
===================================================
How to get this answer:
A pentagon has 5 sides. If each side is the same length, then each side is 20/5 = 4 feet long. That halves to 4/2 = 2 feet. Each side is now 2 feet long, and there are 5 total sides, so 2*5 = 10 feet is the new perimeter.
A shortcut is to simply divide the perimeter in half to get 20/2 = 10. The reason why this works is because the perimeter is the sum of all the sides, which are all being cut in half.
-----
Algebraically, if we had the five sides a,b,c,d,e then
P = a+b+c+d+e
is the perimeter
Cutting each side in half gives
0.5*a+0.5*b+0.5*c+0.5*d+0.5*e = 0.5*(a+b+c+d+e) = 0.5*P
showing that we've cut the perimeter in half.
