0.6 x 100 = 60
Answer:
4 horses and 8 ducks.
Step-by-step explanation:
Let the number of ducks be d and the number of horses be h.
d + h = 12
Now ducks have 2 feet and horses have 4 so:
2d + 4h = 32
Multiply the first equation by 2
2d + 2h = 24
Subtract this equation from the second equation:
4h - 2h = 32 - 24
2h = 8
h = 4.
So there were 4 horses and 12 - 4 = 8 ducks.

Answer:
$55.20
Step-by-step explanation:
Create a proportion where x is the cost of 12 lbs of walnuts:
= 
Cross multiply and solve for x:
0.75x = 41.4
x = 55.2
So, for 12 lbs of walnuts, it will cost $55.20
Answer:
y = 38°
Step-by-step explanation:
If Angle x and angle y are complementary, then x + y = 90°
Also, if angle x is supplementary to a 128 angle, then x + 128° = 180°.
Solving the latter equation for x, we get x = 52°.
Therefore, by the first equation, x + y = 90° becomes 52° + y = 90°, yielding
y = 38°
