You circle the points on both sides and then you calculate them and get what you need...
The answer is c.
Since a^2+b^2=c^2, b^2=c^2-a^2 thus,
16=4-b^2= srt. of 12
Your answer should be the 3rd choice. There is no solution.
Remark
Let the pigs = p
Let the chickens = c
Givens
30 heads is another way of saying that there were 30 creatures in the barnyard. In addition each chicken has 2 legs and each pig has 4
c + p = 30
2C + 4P = 100 (2) Divide (2) by 2
C + 2P = 50 (3) Subtract (1) from (3)
<u>C + P = 30</u>
P = 20
So there were 20 pigs.
Answer:
A.4
Step-by-step explanation:
Because 4/12 is simplified to 1/3 and 2/4 would be simplified to 1/2. 1/2 > 1/4
