<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.

You’re answer should be 60
PQ is bisected by RS at R. It means that PRQ is a line segment with PR = RQ and each of half of PQ.
RQ = PQ/2 = 1/2 [ 4 3/4 ] = 1/2 * 19/4 = <em>19/8 </em> = 2 3/4
Options :
A cookies per pound
B. O pounds per hour
c. cookies per hour
D. hours per cookie
Answer: C.) Cookies per hour
Step-by-step explanation:
Given the following :
Number of cookies baked = 225 cookies
Total time taken = 5 hours
Amount of sugar used = 8 pounds
Tara divides 225 by 5; 225 / 5 = 45
Rate gives the amount or number of times something occurs within a given period, Hence
The rate obtained by Tara corresponds to the ratio of ; (Total cookies baked / total time taken) = (225 / 5), this translates to the amount or number of cookies baked within an hour.
