O 7 children's tickets and 30 adult tickets were sold
O 30 children's tickets and 7 adult tickets were sold
O When 7 tickets are sold, $30 is collected
O (30, 7) is not a possible solution
The correct option 2 that is 30 children's tickets and 7 adult tickets were sold.
Given : A graph which has adult tickets in the x - axis
and children tickets in the y - axis
The marked point is ( 30, 7 )
this means that the value of x axis 30 and y axis is 7
thus from the above information it is clear that there are 30 children's tickets and 7 adult tickets were sold.

a) State what method he was using to solve the equation.
b) Explain where in his work he had a mistake.
c) Show how to fix his mistake and what the correct answer should be.
The method Josh was using to solve the equation is completing the square method.
Josh made mistake where he was supposed to find the square root of both sides.Josh should fix his mistake by finding the the square root of both sides and the correct answer should be x = 1 or -7How to solve quadratic equation?x² - 6x -7 = 0
a = 1
b = -6
c = -7
x² - 6x = 7
Find the half of b and square it, then add to both sides
x² - 6x + 9 = 7 + 9
factorize the expression on the right
(x - 3)² = 16
Find the square root of both sides(x - 3) = √16
x - 3 = ± 4
x = 4 - 3 or x = -4 - 3

Tonio works for a website that sells theater tickets and receives a base salary of $18,200 per year. He earns a commission of 2.3% for all ticket sales, which average $15,500 per week. He also gets a "viewed” fee of 3 cents each time someone comes to the website, whether or not any tickets are purchased. The number of visitors to the website averages 12,400 per month a) what is the total commission Tonio will earn this year. b) What is the total amount Tonio earns from visits to the website?c) What are Tonio’s total earnings for the year?
Tonio's salary is composed by:
- A base value of $18,200.
- A commission of 2.3% for all ticket sales, which average $15,500 per week. Hence 52 x 15,500 per year, as a year has 52 weeks.
- Another commission of $0.03 per visitor to the website, which averages 12,400 per month, hence 12 x 12,400 per year, as a year has 12 months.
Then, the total commissions are given by:
T = 0.023x52x15500 + 0.03x12x12400 = 23002
Tonio will earn a total of $23,002 in commissions this year.
Total amount Tonio earns from visits to the website: 0.03x12x12400 = $4464
Tonio’s total earnings: $18,200 + $23,002 = $41202
Two angles are supplementary.
The measure of the larger angle is four more than three times the measure of the smaller angle. Find the measures of both angles.
Answer:
44° and 136°
Step-by-step explanation:
let x represent the smaller angle then larger angle is 3x + 4
supplementary angles sum to 180° , so
x + 3x + 4 = 180
4x + 4 = 180 ( subtract 4 from both sides )
4x = 176 ( divide both sides by 4 )
x = 44
3x + 4 = 3(44) + 4 = 132 + 4 = 136
then
smaller angle = 44° and larger angle = 136°

You run m miles on Monday, the same amount on Tuesday, and 3 miles on Wednesday. Write an expression in the simplest form that represents the total amount in each situation.
(please show work)
The mean, or average, is equal to the sum of all the miles divided by the number of terms you added together. We have 4 terms that will be added, but are missing one term. We will solve for the missing term by setting up an equation for the average and solving for x, the number of miles you must run on Thursday.
3 = (2 + 3 + 4 + x) / 4
12 = 2 + 3 + 4 + x
12 = 9 + x

Find the parallel line for (2,0) y=-5x+3
The linear equation parallel to y=-5x+3 is:
y = -5*x + 10
How to find the parallel line?Two lines are parallel if and only if both lines have the same slope.
Remember that the general line is:
y = m*x + b
Where m is the slope and b is the y-intercept.
So a line parallel to:
y = -5x + 3
Must have a slope equal to -5, so our line is:
y = -5*x + b
To find the value of b we use the fact that the line passes through (2, 0), then:
0 = -5*2 + b
0 = -10 + b
10 = b
Then the line is:
y = -5*x + 10

a bag of 13 marbles contains 5 marbles with red on them, 6 with blue on them, 7 with green on them and 5 red and green on them....... I'll take a picture of the rest of the question
We have to calculate the probability that we choose a marble that has either red or green on it.
We have a total of 13 marbles.
We can draw a Venn diagram to look at the green and red marbles:
We can see in the diagram that is expected to all the marbles that have red on it to have also green, because they are not mutually exclusive.
Then, we can calculate the probabilities as:
[tex]\begin{gathered} P(G\cup R)=P(G)+P(R)-P(G\cap R) \\ P(G\cup R)=\frac{7}{13}+\frac{5}{13}-\frac{5}{13}=\frac{7}{13} \end{gathered}[/tex]NOTE: If we write the exact color of each marble we will get:
1) 6 blue marbles
2) 2 only green marbles, as 5 of the 7 marbles that have green are "red and green" marbles.
3) 0 only red marbles: all 5 of the marbles that have red are "red and green"marbles.
4) 5 red and green marbles.
Then, if we add, we get 6 + 2 + 5 = 13 marbles.
The marbles that have red or green are: 2 green and 5 red and green, so there are 7 marbles that have red or green.
Then, the probability is equal to number of successful events / total events = 7/13.
It is the same result as the previous calculation.
Answer: the probability is 7/13.

What is addition?One of the four fundamental operations in mathematics is addition, along with subtraction, multiplication, and division. The total amount or sum of the two whole numbers is obtained by adding them. Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more numbers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation. When you add two or more numbers together, you get the sum of the numbers. The sum is the outcome of adding two or more numbers.
Here,
The final score will be the sum of all scores after 5th turn.
initial score=500
first round=−550 points
second round=−150 points
third round=350 points
fourth round=1,150 points
500+-550+-150+350+1150
