Answer:
There were 40 student tickets sold.
Step-by-step explanation:
First I set up equations to represent this situation.
4x+3y=380
x+y=105
x represents the adult tickets and y represents the student tickets.
I can solve this with the elimination method. I want to cancel out the x so I will multiply every term in equation 2 by -4.
4x+3y=380
-4x-4y=-420
Now I combine like terms.
-y=-40
I can divide the negative one from both sides.
y=40
I think that the answer is "A"

Answer:
Step-by-step explanation:
10/7 x 9/8 = 90/56 = 45/28.
7/9 x 8/10 = 56/90 = 28/45
If you want to multiply these, the answer is (28*45) / 28/45) = 1.
