Answer:
8 ducks, 12 cows
Step-by-step explanation:
Let the ducks be x in number and cows be y in number
ATQ, x+y=20 and 2x+4y=64, solving we get y=12 and x=8.
Answer:
b
Step-by-step explanation:
Let x represent the number of quarts of Tuscan sauce and
y represents the number of quarts of marinara sauce Tiffany makes.
A quart of Tuscan sauce requires 6 tomatoes and 1 cup of oil
x quarts requires 6x tomatoes and 1x cups of oil
A quart of her marinara sauce requires 5 tomatoes and 1.25 cups of oil
y quarts requires 5y tomatoes and 1.25 y cups of oil
She has 45 tomatoes and 10 cups of oil on hand.
So the constraints are
6x+5y≤45
1x+1.25y≤10
x>=0 and y>=0
After drawing a diagram of what's required to make 1 quart of Tuscan and 1 quart of Marinara sauce, you can more clearly choose answer choice (B) 6x + 5y < (or equal to) 45, x + 5/4y < (or equal to) 10, x>(or equal to)0, y>(or equal to)0.

Answer:
12.
Step-by-step explanation:
The given equation is
It can be written as
...(i)
The standard form of a circle is
...(ii)
where, (h,k) is center and r is radius.
From (i) and (ii), we get
The center of circle is (-5,2) and radius is 10. So, the maximum value of y is
Therefore, the maximum value of y is 12.
