Answer:
23x+10y
Step-by-step explanation:
add all x variables and all y variables together
First, x+y=60 and solve for x
x= 60-y
Then set up the equation 11x+6y=460
Since, x=60-y, you plug in for y
11(60-y)+6y=460
660-11y+6y=460
660-5y=460
660-660-5y=460-660
-5y=-200
Divide both sides by 5 (you can drop the negative because they are both negative)
5y/5 = 200/5
y=40
Then take y & plug it back into the original equation of:
x+y = 60 (solve for x)
x+40=60
x+40-40=60-40
x=20
The answer is 20 adult tickets (x) and 40 child tickets (y) were sold.

Answer:-30
Step-by-step explanation:
Third term=a3
an=a(n-1) x (-9)
a3=5/3 x (3-1) x (-9)
a3=5/3 x 2 x -9
a3=(5x2x-9)/3
a3=-90/3
a3=-30
