Answer:
C. 8
Step-by-step explanation:
Write in exponential form: (x-8)²=0
Set the base equal to 0: x-8=0
Move the constant (8) to the right: x=8 (answer)
(x-8)(x-8)=0
(x-8)²=0
x-8=0
x=8
Answer:
- 28 general admission
- 26 student
Step-by-step explanation:
Let g represent the number of general admission tickets sold. Then the revenue is ...
3g +2.50(54-g) = 149
.50g = 14 . . . . . . . . . . . subtract 135
g = 14/.5 = 28 . . general admission tickets sold
54-g = 26 . . . . . student tickets sold

Answer: the speed of the current is 0.6 mph
Step-by-step explanation:
Let x represent the speed of the current.
James is kayaking. He can row 3 mph in still water. If he can travel 6 miles downstream. Assuming he went with the current, it means that his total speed while travelling downstream is (3 + x)
Time = distance/speed
Time taken to travel downstream is
6/(3 + x)
In the same amount of time, he can travel 4 miles upstream. Assuming he went against the current, it means that his total speed while travelling downstream is (3 - x). Time taken to travel upstream is
4/(3 - x)
Since the time is the same, then
6/(3 + x) = 4/(3 - x)
Cross multiplying, it becomes
6(3 - x) = 4(3 + x)
18 - 6x = 12 + 4x
4x + 6x = 18 - 12
10x = 6
x = 6/10
x = 0.6 mph
