Question 1Let number of adult tickets - x, student tickets - yRequired equations:
x + y = 87.25x + 5.50y = 52.75Solve by substitution x = 8 - y
7.25(8 - y) + 5.50y = 52.7558 - 7.25y + 5.50y = 52.751.75y = 5.25y = 5.25/1.75y = 3Find x:
x = 8 - 3 = 5Answer: 5 adults and 3 students
Question 2Pair of gloves costs- x, hats cost- yEquations:
2x + 4y = 432x + 2y = 30Solve by elimination, subtract the equations:
2y = 43 - 302y = 13y = 6.5Find x:
2x = 30 - 132x = 17x = 8.5Answer: Gloves cost $8.5, hats cost $6.5

Leon has $50 in a savings account that earns 10% interest, compounded annually. To the nearest cent, how much interest will he earn in 2 years?
Answers
Answer:
$10.50
Step-by-step explanation:
Interest = future value - amount saved
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
$50 x (1.1)^2 = $60.50
Interest = $60.50 - $50 = $10.50

Write an
algebraic expression to represent the area of the shaded region:
2y
4y + 3
Answers
Answer:
4y^{2}+3y
Step-by-step explanation:
First you need to distribute the values.
(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials
You Should get
8y^{2}+6y
Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.
8y^{2}+6y/2
Doing this you will get
4y^{2}+3y

For a school fundraiser, Jessica will make T-shirts. She will order T-shirts and print graphics on them. Jessica must spend $255 on a printing machine and
$6.80 per shirt for the blank shirts, Ink, and other supplies.
Part
What is the maximum number of T-shirts Jessica can make with a budget of $1,000?
Explain your answer or show your work:
Answers
1000-255= 745
You then divide the 745 by the cost of making each shirt,
745/6.80= 109.56
Since you can’t make .56 of a shirt, and the budget says we can’t round up, you can only make 109 shirts.

In an endurance race, Alyson rode her bicycle 7 miles less than Jeff. Together they rode 39 miles. How far did Alyson ride?
Answers
Answer:
Distance cover by Alyson = 16 miles
Step-by-step explanation:
Given:
Distance cover together = 39 miles
Assume;
Distance cover by Jeff = a
Distance cover by Alyson = a - 7
Find:
Distance cover by Alyson
Computation:
a + (a - 7) = 39
2a - 7 = 39
2a = 46
a = 23
Distance cover by Alyson = a - 7
Distance cover by Alyson = 23 - 7
Distance cover by Alyson = 16 miles

What is the solution for the following system of equations?
2x + y = 7
x - 2y = 6
Answers
I got you bro!
Answer:
{x,y} = {4-1}
You might be wondering how I got this, well here are the steps:
System of Linear Equations entered :
[1] 2x + y = 7
[2] x - 2y = 6
Graphic Representation of the Equations :
y + 2x = 7 -2y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y + 6
// Plug this in for variable x in equation [1]
[1] 2•(2y+6) + y = 7
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
x = 2y+6
y = -1
// Use the y value to solve for x
x = 2(-1)+6 = 4
Solution :
{x,y} = {4,-1}

Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school. If Angela works alone, it will take her five and a half hours. If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
Answers
Answer:
3.08 hours
Step-by-step explanation:
Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours.
If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
This is calculated as:
The Number of hours they worked together = T
1/5.5 + 1/7 = 1/T
= 7 + 5.5/(5.5)(7)
= 12.5/38.5
1/T = 12.5/38.5
Cross Multiply
12.5T = 38.5
T = 38.5/12.5
T = 3.08 hours
The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
[tex]W_1=\dfrac{1}{n}[/tex]
In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,
[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]
If Brandon works alone, it will take him 7 hours. The work done by Brandon in one hour is,
[tex]B=\dfrac{1}{7}[/tex]
The work done in one hour, when the work together,
[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]
Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

yes
Step-by-step explanation:
The side lengths of the triangle are 5, 12, and 5+8 = 13. We can check to see if they satisfy the Pythagorean theorem, which would indicate a right triangle.
5² + 12² = 25 +144 = 169 = 13²
These sides do satisfy the relationship between sides for a right triangle, so angle A is a right angle. That is the case when segment AB is a tangent to the circle.
Yes, AB is a tangent.
