Answer:
6 Chickens
Step-by-step explanation:
Let H represent the number of horses and C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:
2C + 4 H = 32 (Eq. 1)
Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:
C + H = 11 (Eq. 2)
From Eq. 2, solve for the number of chickens:
C + H = 11
C = 11 - H (Eq. 3)
Substituting Eq. 3 in Eq. 1, the number of horses can be determined:
2 C + 4 H = 32
2 ( 11 − H ) + 4 H = 32
22 − 2 H + 4 H = 32
2H = 32 − 22
2 H = 10
H = 5 Eq.4
Putting Eq.4 in Eq.1
2C + 4*5 = 32
2C = 32 - 20
2C = 12
C = 12/2
C = 6
Answer:
60 slices
Step-by-step explanation:
Well, to start you must figure the amount of slices, to begin with. This is 9 x 8
this is = to 72.
Then you take 5/6 of 72/1 by multiplying across. to get 60
The answer is 24 + 0.057
Hope this helps!
Answer:
<em>There are 1700 books in the library.</em>
Step-by-step explanation:
<em>If 28% of the books is non-fiction, that means the remaining 72% of books are fiction.</em>
If 72% of the books are fiction, 1224/72 will give us 1%, which is 17.
If 1% is 17 books, then 17*100=100% of books.
There are 1700 books in the library.
