Answer:
The total square kilometers is 299.
Step-by-step explanation:
Area equals length times width.
The number of rows = 80
number of seats in 1 row = 50
total number of seats is the product of the number of rows and number of seats per row = 80*50 = 4000
Answer:
88 adult tickets were sold
Step-by-step explanation:
3s + 7a = 1102
(s + a = 250)-3
3s + 7a = 1102
+ -3s - 3a = -750 Add these equations together
4a = 352 Divide both sides by 4
a = 88
Now plug this into the second equation
s + a = 250
s + 88 = 250
- 88 - 88 Subtract 88 from both sides
s = 162
