At a regional soccer tournament, tickets for two adults and seven students cost $60. Tickets for three adults and eleven students cost $93. Determine the price of an adult ticket and the price of a student ticket.
The price of an adult ticket is $, and the price of a student ticket is $
Answer:
The price of an adult ticket is $9 and the price of a student ticket is $6
Step-by-step explanation:
Create a system of equations where x is the price of an adult ticket and y is the price of a student ticket:
2x + 7y = 60
3x + 11y = 93
Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2, to cancel out the x terms:
6x + 21y = 180
-6x - 22y = -186
Add them together:
-y = -6
y = 6
Then, plug in 6 as y into one of the equations to solve for x:
2x + 7y = 60
2x + 7(6) = 60
2x + 42 = 60
2x = 18
x = 9
So, the price of an adult ticket is $9 and the price of a student ticket is $6

What is the solution to this system of equations?
o 14. - 1/2)
0 (4,-
Ono solution
infinitely many solutions
Answer:
one solution
Step-by-step explanation:
Given the equations
1/4x + 1 1/2y =5/8 ..... 1
3/4x - 1 1/2y =3 3/8 ..... 2
Get the value of x
Add both equations
1/4x + 3/4x = 5/8+3 3/8
4x/4 = 5/8+27/8
x = 32/8
x= 4
Substitute x = 4 into equation 1
From 1;
1/4x + 1 1/2y =5/8 .
1/4(4) + 3/2 y = 5/8
1 + 3/2 y = 5/8
3/2 y = 5/8 - 1
3/2 y = -3/8
Cross multiply
24y = -6
y = -6/24
y = -1/4
Hence the solution {x,y) is (4, -1/4)
The system has only one solution

how do you work out the percentage increase
The cost of a pair of shoes is Rs. 1000 . The GST charged was '5%' . Find the bill amount andalso find share of CGST, and SGST.
Answer:
Bill amount = Rs. 1050
CGST share = SGST share = Rs. 25
Step-by-step explanation:
We are told that the GST charged was 5% and cost of a pair of shoes is Rs. 1000. Thus;
Bill amount = 1000 + (5/100) × 1000
Bill amount = Rs. 1050
Now, CGST and SGST are both usually half of GST rate.
Thus;
CGST rate = SGST rate = 5%/2 = 2.5%
Thus;
CGST share = SGST share = 2.5% × 1000 = Rs. 25

Margo can purchase tile at a store for $0.69 per tile and rent a tile saw for $36. At another store she can borrow the tile saw for free if she buys tiles there for $1.29 per tile. How many tiles must she buy for the cost to be the same at both stores?
Answer:
30 tiles need to buy for same cost in both store.Step-by-step explanation:
Let x be the number of tiles to buy for same cost in both store.
18+0.69 · n = 1.29 · n,
1.29n -0.69n =18 or
0.6n =18
n =18/0.6=30
Therefore, 30 tiles need to buy for same cost in both store.[Ans]

A triangle has sides of length 2 cm, 8 cm and 9 cm.
Calculate the value of the largest angle in this triangle.
:)
Answer:
113.97 degrees
Step-by-step explanation:
use the cosine rule for finding an angle
cosA = b^2 + c^2 - a^2
2bc
In the given triangle angle A is greatest than any other angle.
What is the triangle?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
Given sides of triangle, a=2cm,b=8cm,c=9cm
cosine law
Cos A = [tex]\frac{-a^2 + b^2 + c^2}{ 2bc}[/tex] = [tex]\frac{64 + 81 - 4 }{2 * 8 *9}[/tex] = 141/ 144
Cos B = [tex]\frac{a^2 - b^2 + c^2}{ 2ac}[/tex] = [tex]\frac{4 + 81 - 64}{2 * 2 *9}[/tex] = 21/36
Cos C = [tex]\frac{a^2 + b^2 - c^2}{ 2ab}[/tex] = [tex]\frac{4 + 64 -81}{2 * 2* 8}[/tex] = -13/52
A = Cos⁻¹ (141 /144 )
B = Cos⁻¹ (21/ 36 )
C = Cos⁻¹ (-13/52 )
Thus Angle A < Angle B < Angle C.
Therefore, Angle A is the greatest in the triangle.
