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:

The shape of the cross section is a triangle. Therefore, the answer is the second option: Triangle.
A rectangular pyramid is a pyramid that has a rectangle as its base. Therefore, its base has four sides. The rectangular pyramid also has four triangles that coming together in its apex. So, if the rectangular pyramid is<span> sliced so the cross section is perpendicular to its base and passes through its vertex, the cross section obtained is a triangle.</span>
I believe this is how you do it...
AI=5, 5 squared=25
IF=12, 12 squared=144
144+25 (only because line A F is bigger than AI or IF does it add)
A F=169
