Answer:
The price of the admission is 15.
Step-by-step explanation:
From the information given, you can write the following equations:
a+3e=45 (1)
a+5e=65 (2), where:
a is the admission cost
e is the exhibition cost
First, you can solve for a in (1):
a=45-3e (3)
Second, you can replace (3) in (2):
45-3e+5e=65
45+2e=65
2e=65-45
2e=20
e=20/2
e=10
Finally, you can replace the value of e in (3):
a=45-3e
a=45-3(10)
a=45-30
a=15
According to this, the price of the admission is 15.
It's a cube so x should also equal 6
The total cost is $22.28, rounded to the nearest half dollar is $22.50.
3x3x3x3x3 and so on that’s how the powers work you would have to multiply 3 times itself 20 times I sure hope this helps 3 to the 20th power would equal 3486784401
