Answer:
52 students
Step-by-step explanation:
Let's assume A represents number of students in the library means A=86,
B represents number of student in student union means B = 78
U represents total students surveyed means U = 136
section II represents number of students in library and student union means
II = 34
Now from figure we can see
number of students only in library is represented by section I .
and section I can be written as
I = A - II
I = 86-34 = 52
only in Union represents III
III = B - II
III = 78-34 = 44
not in library or not in union = U - (I + II + III)
= 136 - (52+ 34+ 44)
= 136 - 130 = 6

Answer:
x=7222285
y=0.00015646779
Step-by-step explanation:
6482647+739638=72836y(5396-(-628333)=x
7222285=72836y(5396+628333)=x
7222285=72836y(633729)=x
x=7222285
72836y(633729)=7222285
72836*633729*y=7222285
46158285444*y=7222285
y=7222285/46158285444
y=0.00015646779
We have that
<span>50% of A is equal to $0.5a
0.50A=0.5a----------> A=a
and
</span><span>20% of B is equal to $0.2a
0.20B=0.2a---------> B=a
so
A=B
the answer is
A=B</span>
