a and c i think 
the blue circle is all the people who had brothers one name was in the blue circle so one person had a brother but the in between part of the too circles are who had both a brother and a sister so the is one name in the between purple  so you count that one to for brother and for sisters
 there were  2 people that had brother 
  and four people that had sisters
and one that had both 
 
        
             
        
        
        
Answer:
2/3 ounces
Step-by-step explanation:
one pound is 16 ounces
1/3 of 16 ounces is 16/3
(16/3) ÷ 8 = (16/3) * (1/8) = 2/3
 
 
        
             
        
        
        
Answer:
The lines are parallel, with the same slope of 5. 
Step-by-step explanation:
Remember that if slopes are the same, then the lines are parallel. If the slopes are opposite reciprocals, they are perpendicular. If they are neither of those cases, then they would be neither. 
1) Since y = 5x + 1 is already in slope-intercept format (y = mx + b, in which m represents the slope) we know that 5 is the slope of that equation. 
2) To find the slope of -5x + y = 6, let's just convert it to the slope-intercept format by isolating y on the left side like so: 

(All you need to do is move -5x to the right side of the equation.) So, by looking at y = 5x + 6, we can do the same thing we did from step 1 and find that the slope is 5. 
3) Since both of the equations' slopes are 5, they share the same slope - therefore, they are parallel. 
Hope this helps! Please do not hesitate to ask any questions.
