Answer:
2,100 $28 tickets were sold, and 3,900 $40 tickets were sold!
Step-by-step explanation:
So, we need to write two equations in order to solve this:
We will think of 28 dollar tickets as x, 40 dollar tickets as y.
Now lets make those equations:
and
Now, to solve for x and y, lets set a value for x or y. In this case I will set the value of y:
I will do this by taking , and subtracting x to the other side, to get y alone:
Now lets plug in y to our second equation:
=
Now combining like terms and solving for x we get:
=
=
Now that we know x, lets solve for y by plugging into our first equation!
=
So now we know that our answer is:
2,100 $28 tickets were sold, and 3,900 $40 tickets were sold!
Hope this helps! :3
If the polygons are similar, then we can set up a similarity ratio using sides AB and EF and any other 2 sides where both side lengths are given. That appears to be true for sides BC and FG. Our similarity ratio would be this then, going from the bigger polygon stuff on top and the smaller polygon stuff on bottom:
.
If we cross multiply we have 8y = 36 and divide both sides by 8 to get that y = 4.5. There you go!
