let's take admission fee= z
8z+11z=17.50+21.25
19z=38.75
z=38.25/19
z=2.4 (aprox)
Or In case of Kiara 17.50 amount paid in 8 rides
.so 1 ride=17.50/8
=2.1875
same In case of mia 
so 1 ride=21.25/11
=1.9318. 
but, they are not match so there is problem in your Questions.
 
        
             
        
        
        
Answer:
x = 2.5 inches. Or
x = 5/2
Step-by-step explanation:
Length: 7 + 2x
Width: 5 + 2x
Note that you have to add x at each end of the picture and onto each part of the width.
The entire area is 120 square inches.
Formula
L*W = Area
(2x + 7)(2x + 5) = 120
Solution
4x^2 + 10x + 14x + 35 = 120                Subtract 120 from both sides. Add xs
4x^2 + 24x + 35 - 120 = 0
4x^2 + 24x - 85 = 0                             Factor
(2x + 17)(2x - 5)
2x + 17 has no meaning. It will give -  8.5 which is not possible.
2x - 5 =0
2x = 5                                                  Divide by 2
x = 5/2
x = 2.5
Note: I don't know which one the computer is looking for.
 
        
                    
             
        
        
        
Answer:
It's irrational
Step-by-step explanation:
the square root of 27 is equal to:

We know that  is an irrational number (but a real number), so
 is an irrational number (but a real number), so  is the same.
 is the same.
In case we need to prove that  is irrational, please leave a comment.

Answer:
x   ≤ 8
Step-by-step explanation:
Given
2x - 4 ≤ 12
Isolate the term in x by adding 4 to both sides
2x ≤ 16 ( divide both sides by 2 )
x ≤ 8 ← is the solution
 
        
                    
             
        
        
        
So to rewrite it so that we can find the side, we just need to isolate the a variable.

So firstly, divide by 6 on both sides of the equation: 
Next, square root each side, and your answer should be
