<span>There are 4 long rows and 5 short rows in the theater. x represents the number of chairs in each long row and y represents the number of chairs in each short row.
So, total number of chairs in 4 long rows= 4x
Total number of chairs in 5 short rows = 5y
Total number of chairs in the theater on a normal day = 4x + 5y
When 2 chairs are added to each long row, the number of chairs will change to (x+2).
So, total number of chairs in 4 long rows will be = 4(x+2)
When 3 chairs are added to each short row, the number of chairs will change to (y+3)
So, total number of chairs in 5 short rows will be = 5(y+3)
Thus, total number of chairs in the theater in rush day = 4(x+2) + 5(y+3)
= 4x + 8 + 5y + 15
= 4x + 5y + 23
Thus we can say the number of chairs increase by 23 as compared to a normal day.

Answer:
8 1/8 hours
Step-by-step explanation:
Jerry played with 3 friends today, all at different times.
Tommy = 1 7/8 hours
Nathan = 1 3/4 hours
Chris = 3 3/2 hours
How many hours did Jerry play with his 3 friends today?
Number of hours Jerry play with his 3 friends today = 1 7/8 + 1 3/4 + 3 3/2
= 15/8 + 7/4 + 9/2
= (15+14+36)/8
= 65/8
= 8 1/8 hours
