The regular price of a child's ticket is $51
<u><em>Explanation</em></u>
If
represents the regular price of an adult ticket, then the regular price of a child's ticket 
Given equations is: 
<u>Solving the above equation</u>, we will get...

So, the regular price of a child's ticket
dollar.
To solve for x, we need to get all our constants on one side of the equal sign and all our variables on the other side of the equal sign.
3x - 24 = 81
3x -24 + 24 = 81 +24
3x = 81 + 24
3x = 105
3x/3 = 105 / 3
x = 105 / 3
The probability that the the sample mean would be less than x=132.25 will be calculated as follows:
z=(x-σ)/μ
μ- mean
σ- standard deviation
z=(132.25-138)/28=-0.2054
thus:
P(X≤x)=0.4207=42.07%
Answer:
x= 11
Step-by-step explanation:
4x+5/7 =2x-1/3
multiply both of the equation by 7 first
4x+5/7 times 7 = 2x-1/3 times 7
4x+5= (2x-1)7/3
now multiply 3 to both sides
3(4x+5)= (2x-1)7/3 times 3
3(4x+5)= (2x-1)7
now you should distribute on both sides
(4x times 3)+(5 times 3)= (2x times 7)-( 1 times 7)
12x+15= 14x-7
subtract 12x from both sides
12x-12x+15= 14x-12x-7
15= 2x-7
add 7 to both sides
15+7= 2x-7+7
22= 2x
divided both sides by 2
22/2 = 2x/2
11=x
