Answer:
Step-by-step explanation:
A theatre has 4 chair in a row; lets draw that out
Let's pretend that this is a chair: ♦
So we have 4 chairs in a row
♦ ♦ ♦ ♦
And there are 5 rows
♦ ♦ ♦ ♦
♦ ♦ ♦ ♦
♦ ♦ ♦ ♦
♦ ♦ ♦ ♦
♦ ♦ ♦ ♦
Let's find the perimeter;
4 + 5 + 4 + 5
=18
The perimeter is 18 rows.
The first one is (z-7)(z-1)
second: (x+1/3)(x+1/3)
third: (x-1/5)(x-1/5)
fourth: (x-5)(x-2)
Answer:
- 321 adult tickets
- 227 child tickets
Step-by-step explanation:
This sort of problem is easily solved by defining a variable to be the quantity of the higher-value contributor. Here, we can let x represent the number of adult tickets. Then total revenue is ...
6.50x +3.50(548-x) = 2881
3x +1918 = 2881 . . . . . . . . . . . . eliminate parentheses, collect terms
3x = 963 . . . . . . . . . . . . . . . . . . subtract 1918
x = 321 . . . . . . . . . . . . . . . . . . . . divide by 3
548-x = 548 -321 = 227 . . . . . .number of child tickets
321 adult tickets and 227 child tickets were sold.
The polygon would have 18 sides. Hope this helps!
