My answer would be D, but I am not sure.
Answer:

Step-by-step explanation:
Area = L x W
5/9 = 2/3 * W
5/9 ÷ 2/3 = W
5/6 = W
1 - 0.16 = 0.84
21/0.84 = 25
25 grams of fiber should be consumed daily.
The answer is power of 10
Answer:
B) 16 . . . . the value of Z
Step-by-step explanation:
The problem statement tells us that ...
... x = y +12
... z = y - 8
Then x - z = (y +12) -(y -8) = 20.
In ratio units, we have ...
... x:z = 9:4
The difference of these in ratio units is 9-4 = 5, so each ratio unit must stand for 20/5 = 4 units of X, Y, or Z. Hence ...
... Z = 4·4
... Z = 16
_____
<em>Check by finding the other values</em>
... X = 9·4 = 36
... Y = X -12 = 24 = Z +8 . . . . yes
