Answer:
2x - xy = 0
Step-by-step explanation:
We need to solve the equations simultaneously to find the values of x and y:
x + y = 12
x - y = 8 - we need to add the equations together
2x = 20
x = 10
Then we substitute x into one of the equations to find y:
10 + y = 12
12 - 10 = y
y = 2
Now we substitute x and y into the final expression:
2(10) - 2(10)
20 - 20 = 0
Surface are of a rectangular prism = 2(l x w + l x h + w x h) = 2(10 x 3 + 10x + 3x) = 2(30 + 13x) = 60 + 26x
Volume of a rectangular prism = l x w x h = 10 * 3 * x = 30x
Since surface area = volume
60 + 26x = 30x
4x = 60
x = 15 in

Answer: 475 adults paid admission
Step-by-step explanation:
1.50c+4a=5050 (1.50 per child and 4 per adult)
1.50(2100)+4c=5050 (2100 children times 1.5 each)
3130+4a=5050
4a=1900
a=475
