Answer:
r=1
Step-by-step explanation:
-7.61 - 4.3r = -8.1r - 3.81
(bring like terms to one side)
-4.3 r = -8.1r -3.81 + 7.61
-4.3r + 8.1 r =-3.81 + 7.61
(consolodate)
3.8r = 3.8
(divide right by # of r)
r = 3.8/3.8
r = 1

Answer: Choice B</h3><h3>{4,5,6,7}</h3>
====================================================
Explanation:
Set A = {4,5,6,7,8,9} since these values are larger than 3 and smaller than 10. We only consider whole numbers in this range.
Set B = {1,2,3,4,5,6,7} represents positive whole numbers less than 8
To find the set 
we need to see which values are in both A and B at the same time. Those values are {4,5,6,7}
So 
--------
side note: the notation means "A intersect B", so we're looking at where the two sets intersect or overlap (ie what they have in common).
