A. w= -22 so A has a negative solution.
D doesn't have a variable so I'm not sure about it (did you type it correctly?), but because only one side of the equation has a negative number, I'm guessing D is also a negative solution
Answer:
It is 1/11

Answer:
100°
Step-by-step explanation:
two angles are supplement .
if their sum is equal to 180°
supplement angle of 80° + x = 180°
180° - 80° = 100° answer
Answer: 0.2643
Step-by-step explanation:
Let p be the population proportion and 
be the sample proportion .
As per given question , we have
z-score : 
The required probability ( using z-table ):-
Hence, the probability that the proportion of books checked out in a sample of 478 books would be less than 13% = 0.2643

Answer: 1/4 mile</h3>
Explanation:
A square has all four sides the same length. So the length and width are the same.
We can see that (length)*(width) = (1/4)*(1/4) = 1/16 square miles.
If you wanted, you could solve for W in (1/4)*W = 1/16 and you should get W = 1/4.
