Adult tickets cost $4 more than student tickets, if you know that Robert bought 5, then you can multiply 5x4. You can then subtract those $20 from the total of $104, which would bring you to a total of $84. Then you can add the the 5 adult tickets to the 7 student tickets, which would give you a total of 12 tickets. You can then do 84/12= 7 since the cost of every ticket is now equal. Add 4 to the 7 for the cost of the adult ticket. You now have $11 as the cost of an adult ticket and $7 as the cost of a student ticket. Plug everything in to 5a + 7s = 104 if you want to verify the answers. ( a=adult, s=student)

V≈1809.56
Step-by-step explanation:
The measure of the other side of a quadrilateral is
cm.
In the given quadrilateral one side is unknown we need to find the unknown side.
By dividing the given quadrilateral into a rectangle and a triangle we can find the other side.
<h3>What is Pythagoras theorem?</h3>
The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides. That is,
.
Now, 
⇒
Therefore, the measure of the other side of a quadrilateral is
cm.

Answer:
81 books
Step-by-step explanation:
If you divide 731 into 9 you'll get 81.2
so that means you have 2 books left over that wont be on the shelf
so you'll have to round to 81
17 3/4 - 2/5x = 4 1/2
-2/5x = 4 1/2 - 17 3/4
-2/5x = 9/2 - 71/4
-2/5x = 18/4 - 71/4
-2/5x = - 53/4
x = (-53/4) / (-2/5)
x = -53/4 * - 5/2
x = 265/8
x = 33 1/8 bottles
