I think boys =18
girls=12
boys :x
girls:y
student:z
the number of group for the boys :n
the numberof group for the girls :m
so x=(3/5)*z
y=(2/5)* z
x/y=3/2
3y-2x=0
(1/10)*z*n=(3/5) *z
so n=6
(1/5)*z*m=(2/5)* z
put x=(1/10)*z*6
y=(1/5)*z*2
into 3y-2x=0 and z=30
z=30 so x=(1/10)*30*6=18
y=(1/5)*30*2=12

We need to simplify
First lets factor
=
by applying the radical rule
By applying the radical rule
So
=
=
Now let's factor
By applying the radical rule
,
So
=
So
=
We know that
so
We now have
We know that
So
We now got
We can notice that the numerator and the denominator both got √2 in a multiplication, so we can simplify them, and we get:
All in All, we get
=
Hope this helps! :D
Answer: 1,208 seats
Step-by-step explanation:
39-18= 21
18 x 478 = 8,604
21 x 292 = 6,132
8,604 + 6,132 = 14,736
14,736 - 13,528 = 1,208
