b. At the circus, three adult tickets and five child tickets cost $51, and five adult tickets
and two child tickets cost $47. Which system of linear equations below can be used to
determine the price of each ticket?
Let x represent the cost of an adult ticket, and let y represent the cost of a child ticket.
Answers
Answer: x = $7, y = $6
Step-by-step explanation:
Let x be the cost of an adult ticket
Let y be the cost of a children's ticket
Translate these sentences to algebra:
At the circus, three adult tickets and five child tickets cost $51: 3x + 5y = 51
Five adult tickets and two child tickets cost $47: 5x + 2y = 47
Now we have two equations. Let's use substitution to solve.
3x + 5y = 51
3x = 51 - 5y
.: x = 17 - 5y/3
Now substitute this value of x into the second equation to find the numerical value of y:
5(17 - 5y/3) + 2y = 47
85 - 25y/3 + 2y = 47
-19y/3 = -38
-19y = -114
.: y = 6
Now find x:
x = 17 - 5y/3
x = 17 - 10
.: x = 7
So an adult ticket costs $7, and a child ticket costs $6 :)

Answers
Answer:
Choice C
Step-by-step explanation:
We are given the function:
[tex]\displaystyle \large{f(x)=3x+5}[/tex]
Let [tex]\displaystyle \large{y=f(x)}[/tex] therefore:
[tex]\displaystyle \large{y=3x+5}[/tex]
To find an inverse of function, swap the position of x and y:
[tex]\displaystyle \large{x=3y+5}[/tex]
Then solve or simplify the equation in term of y:
[tex]\displaystyle \large{x-5=3y}\\\displaystyle \large{\frac{x-5}{3}=y}\\\displaystyle \large{y=\frac{1}{3}x-\frac{5}{3}}[/tex]
Therefore, the answer is choice C.
__________________________________________________________
Summary
An inverse function is a function that swaps the position of domain and range, defined as notation [tex]\displaystyle \large{f^{-1}(x)}[/tex] or [tex]\displaystyle \large{y^{-1}}[/tex] generally. When finding an inverse function, make sure to swap position of range and domain, if given the interval.
Only one-to-one functions may have an inverse — multiple-to-one can not have an inverse such as quadratic function or any even-degree polynomial functions.

Substitute the given values A = 77 and h = 4 into the

Answers
Answer:
b=19.25
Step-by-step explanation:
Ok, so if you plug in 77 for A and 4 for h, you will get 77=4h. So from here, you have to divide 77 by 4, which is 19.25 and that is the answer for variable b.
Arlington High School recently installed a new black-box theatre for local productions. They only had
room for 14 rows of seats, where the number of seats in each row constitutes an arithmetic sequence starting
with eight seats and increasing by two seats per row thereafter. How many seats are in the new black-box
theatre? Show the calculations that lead to your answer.
Answers
Answer: ANSWER*0.15 (15% is 15/100 or 0.15)
Step-by-step explanation:
An arithmetic sequence is a sequence where the difference between each consecutive term is the same.
The number of seats in the new black box is 294.
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8 is an arithmetic sequence.
We have,
Number of rows = 14
n = 14
a = 8.
d = 2
So,
The number of seats in the 14 rows is,
8, 10, 12, 14,.........
Now,
The sum of the arithmetic sequence.
= n/2 [2a + (n - 1)d ]
The number of seats in the new black box.
= 14/2 [ 2x8 + (14 - 1)2 ]
= 7 [ 16 + 26 ]
= 7 x 42
= 294
Thus,
The number of seats in the new black box is 294.

a bus travelled 63 km in first hour 60 km in second hour and 57 km in third hour what was te Average distance covered in one hour
Answers
The average speed is the ratio of the total distance to the total time. Then the average distance covered in one hour by the bus is 60 kilometers.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distace }{Time }[/tex]
A bus traveled 63 km in the first hour 60 km in the second hour and 57 km in the third hour.
Then the average speed will be
[tex]\rm Average \ speed = \dfrac{Total \ distace }{Total \ time }\\\\\\Average \ speed = \dfrac{63 + 60 +57}{1+1+1}\\\\\\ Average \ speed = \dfrac{180}{3}\\\\Average \ speed = 60 \ km/h[/tex]
The average distance covered in one hour by the bus is 60 kilometers.
