Answer:
D)
Step-by-step explanation:

Answer:
68 chickens and 12 cows.
Step-by-step explanation:
Let x represents the number of chicken and y represents the number of cows in the barnyard,
Given,
Total heads = 80
⇒ x + y = 80 ------(1),
Also, total legs = 184,
Since, a chicken has two legs and cow has 4 legs,
⇒ 2x + 4y = 184 -----(2),
Equation (2) - 2 × equation (1),
We get,
4y - 2y = 184 - 160
2y = 24
y = 12
From equation (1),
x + 12 = 80 ⇒ x = 80 - 12 = 68
Hence, the number of chicken = 68,
And, the number of cows = 12
$48.75 minus $35 would equal 13.75 then you divide by 0.25 that would give you 55 so M=55
1/4 (4/6 - 3/12) = 1/4 (5/12) = 5/48
I’m not quite sure if you are saying each side is 7 or 77 so I did both.
If the side length is 7, then 9.9 is the answer.
If the side length is 77, then 108.9 is the answer.
