a) Matrix B =
Gross Receipt = AB
. =
c) Total revenue is the sum of receipts from 4 cinemas given in part b
Hence,
Total revenue = $2525 + $3620 + $2845 + $3705 = $12,695
Answer:
i have no idea what you mean
Answer:
61
Step-by-step explanation:
If you want only the middle number, then call it x
the largest of the 3 is x + 1
The smallest of the 3 is x - 1
Add
x + 1 + x - 1 + x = 183 Cancel the 1s out.
x + x + x = 183 Combine the like terms on the left
3x = 183 Divide by 3
x = 183/3 Do the division
x = 61
The middle number is 61
I'm pretty sure it's A. 7+x+4y, but I could be wrong.
