You and your friend are selling raffle tickets for a new laptop. you sell 14 more then your friend sells. Together you and your friend sell 58 tickets. Write a system of linear equations that represent this situation. How many did each of you sell?
You sold 36 tickets and your friend sold 22 tickets.
Explanation:Let's represent the number of tickets you sell as x and the number of tickets your friend sells as y.
We know that you sell 14 more tickets than your friend, so we have the equation:
x = y + 14
We also know that together you and your friend sell 58 tickets, so the equation becomes:
x + y = 58
Now we can solve these two equations simultaneously to find the values of x and y.
Substitute the value of x from the first equation into the second equation:(y + 14) + y = 58
Combine like terms:2y + 14 = 58
Subtract 14 from both sides to isolate the variable:2y = 44
Divide both sides by 2 to solve for y:y = 22
Now substitute the value of y back into one of the original equations to solve for x:x = 22 + 14
Simplify:x = 36
Therefore, you sold 36 tickets and your friend sold 22 tickets.

The system of equations representing the problem is y = x + 14 and x + y = 58. Solving this system we get x = 22 (friend's sold tickets) and y = 36 (your sold tickets).
Explanation:We'll use a system of linear equations to model this situation. Let's define x as the number of tickets your friend sells, and y as the number of tickets you sell. From the problem, we know two things:
1. You sell 14 more tickets than your friend: y = x + 14.
2. Together, you and your friend sell 58 tickets: x + y = 58.
To solve this system, we can substitute y in the second equation with x + 14 from the first equation. This gives us:
x + (x + 14) = 58.
Solving this we get x = 22 and substituting x into the first equation gives: y = 22 + 14 = 36.
So, your friend sold 22 tickets, and you sold 36 tickets.

What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is a train that leaves a train station at 1 p.m. it travels at an average rate of 60 mi/hr. A high-speed train leaves the same station an hour later. it travels at an average rate of 96 mi/hr. The second train follows the same route as the first train on a track parallel to the first.
We have -
Assume that the second train catches the first in x hours. Then, we can write -
60(x + 1) = 96x
60x + 60 = 96x
96x - 60x = 60
36x = 60
x = 60/36
x = 5/3 hours
Therefore, the second train will catch up with the first train after 5/3 hours.

Ou work as a cashier for a grocery store and earn $5 per hour. you also mow lawns and earn $10 per hour. you want to earn at least $50 per week, but would like to work no more than 10 hours per week. which system of inequalities, along with y ≥ 0 and x ≥ 0, would you use to solve the real-world problem?
The problem can be represented by two inequalities: one to ensure earning at least $50 per week (5x + 10y >= 50) and another to restrict working to no more than 10 hours per week (x + y <= 10), alongside x >= 0 and y >= 0 to indicate non-negative hours worked for each job.
To determine the system of inequalities to solve the problem, we need to define variables for the number of hours spent on each job. Let's use x to represent the number of hours working as a cashier at the grocery store, and y to represent the number of hours mowing lawns. The student earns $5 per hour at the grocery store and $10 per hour mowing lawns. They want to earn at least $50 per week and work no more than 10 hours in total.
From this information, we can establish the following inequalities:
5x + 10y >= 50 (To ensure earning at least $50 per week)
x + y = 10 (To ensure working no more than 10 hours per week)
Additionally, we include y >= 0 and x >= 0 to represent that the number of hours worked at either job cannot be negative.

A drama club wants to raise at least $500 in tickets sales for its annual show. The members of the club sold 50 tickets at a special $5 rate. The usual ticket price the day of the show is $7.50. At least how many tickets do they have to sell the day of the show to meet the goal. Let t=tickets
To meet their fundraising goal, the drama club needs to sell 34 tickets at $7.50 each.
Answer:
The drama club wants to raise at least $500 in ticket sales. They already sold 50 tickets at $5 each. Let the number of tickets they need to sell at $7.50 be represented by 't'.
Revenue from $5 tickets: $5 × 50 = $250To find the number of $7.50 tickets needed: $500 - $250 = $250Number of $7.50 tickets needed: $250 / $7.50 = 33.33Therefore, the drama club needs to sell at least 34 tickets at $7.50 each to meet their goal.
If 8 times a number is decreased by 20,the result is the same as 3 times the number increased by 80
Final answer:
The algebraic expression for the problem is '8n - 20 = 3n + 80', which simplifies to 'n = 20'. Therefore, the number in question is 20.
Explanation:
The question presents a classic algebra problem where we have to find the value of a variable that satisfies a given condition. Specifically, this problem states:
"If 8 times a number is decreased by 20, the result is the same as 3 times the number increased by 80."
To solve this, we'll convert the words into an algebraic equation and solve for the number. Let's use 'n' to represent the number:
8n - 20 = 3n + 80This equation tells us that when you multiply the number by 8 and subtract 20, it's equal to the result of multiplying the number by 3 and adding 80. To find 'n', we combine like terms and solve:
8n - 3n = 80 + 205n = 100n = 100 / 5n = 20Thus, the number we're looking for is 20.
What value of n would make point A the circumcenter?
1. 2
2. 3
3. 4
4. 5
Answer:
The correct option is 2. The value of n is 3.
Step-by-step explanation:
Circumcenter is the point, where the perpendicular bisectors of a triangle intersect each other.
Circumcenter is also known as the center of the triangle. The distance from circumcenter to each vertex are same.
In triangle DEF, if A is the circumcenter.
[tex]AE=AD[/tex]
[tex]10=2n+4[/tex]
Subtract 4 from both sides.
[tex]10-4=2n[/tex]
[tex]6=2n[/tex]
Divide both sides by 2.
[tex]3=n[/tex]
Therefore the value of n is 3 and option 2 is correct.
Answer:
Option 2 is true
Step-by-step explanation:
We have to find the value of n for which point A becomes circumcenter.
Circumcenter: It is that point where perpendicular bisectors of triangle intersects.
The circumcenter is also knows as center of triangle.
Circumcenter is at equal distance from each vertex of triangle.
If point A is circumcenter then
AE=AD
We have AE=10 units
AD=2n+4
Substitute the value
10=2n+4
[tex]2n=10-4[/tex]
By subtraction property of equality
[tex]2n=6[/tex]
[tex]n=\frac{6}{2}=3[/tex]
Hence, the value of n is 3 would make point A the circumcenter.

25xy4 + 60xy3 5xy 5xy3 + 12xy2 5y2 + 12 5xy + 12y 5y3 + 12y2
the simplified expression is 25xy^4 + 65xy^3 + 22xy + 12xy^2 + 18y + 12y^2 + 5y^3 + 12
To simplify the given expression, we first need to combine like terms. Like terms are those that have the same variables raised to the same powers. In this case, we have terms with x and y raised to different powers.
The expression is:
25xy^4 + 60xy^3 + 5xy^3 + 5xy + 12xy^2 + 5y^2 + 12 + 5xy + 12y + 5y^3 + 12y^2
Now, let's combine the like terms:
Combine the terms with xy^4: 25xy^4
Combine the terms with xy^3: 60xy^3 + 5xy^3 = 65xy^3
Combine the terms with xy^2: 12xy^2
Combine the terms with xy: 5xy + 5xy + 12xy = 22xy
Combine the terms with y^2: 5y^2 + 12
Combine the terms with y: 12y + 5y + 12y^2 = 18y + 12y^2
Combine the terms with y^3: 5y^3 + 5y^3 = 10y^3
Now, let's put all the combined like terms together:
25xy^4 + 65xy^3 + 22xy + 12xy^2 + 18y + 12y^2 + 5y^3 + 12
This is the simplified expression.
The probable question maybe:

A wedge is cut out of a circular cylinder of radius 10 by two planes. one plane is perpendicular to the axis of the cylinder. the other intersects the first at an angle of 30° along a diameter of the cylinder. find the volume v of the wedge, taking rectangular cross-sections to be parallel to the line of intersection of the two planes, which is the x-axis. (let r = 10.)
The volume of the wedge is 50π/3 - 25√3.
Explanation:To find the volume of the wedge, we need to calculate the volume of the cylindrical segment between the two intersecting planes. The formula for the volume of a cylindrical segment is V = h((R^2θ)/2 - (R^2sinθ)/2), where h is the height of the segment, R is the radius of the cylinder, and θ is the angle of the intersection between the planes. In this case, h is 10 and θ is 30°, so the formula becomes V = 10((10^2 * π/6)/2 - (10^2 * sin(π/6))/2). Simplifying the equation gives V = 50π/3 - 25√3.
