These are the correct answer
X = 3/5 , parts of water that are mixed with 1 part of fruit juice
Answer:
See explanation
Step-by-step explanation:
Let c be the number of cows and d be the number of ducks.
c cows have 4c feet, d ducks have 2d feet. In total, c cows and d ducks have
4c + 2d = 148 feet.
Divide it by 2:
2c + d = 74.
This gives us that the number of ducks is even and cannot be 0 (because farmer Brwn has ducks). The minimum possible number of ducks is 2, so the maximum possible number of cows is 36.

Answer:
<h2>66 and 66</h2>
Step-by-step explanation:
opposite angles are equal
12x - 18 = 8x + 10
combine similar terms:
12x - 8x = 10 + 18
4x = 28
x = 28/4
x = 7
plugin the value of x=7 back into the equation to solve the angle
= 12x - 18
= 12(7) - 18
= 66
= 8x + 10
= 8(7) + 10
= 66
K = F + 459.67
Subtract K on both sides:
0 = F - K + 459.67
Subtract F on both sides:
-F = -K + 459.67
Divide each term by -1 so that the variables are positive:
F = K - 459.67
