(40 POINTS) Let x = price of a standard ticket, y = price of a matinee ticket, and z = price of a senior ticket.
150x + 80y + 12z = 2,466
380x + 95y + 48z = 5,419
210x + 130y + 60z = 3,960
220x + 225y = 4,445
540x + 270y = 8,370 → y = −2x + 31
x = 11

Bryan’s hockey team is purchasing jerseys. The company charges $250 for a one-time set-up fee and$23 for each printed jersey. Which expression represents the total cost of x number of jerseys for the team?
1) 23x
(2) 23x + 250
(3) 23 + 250x
(4) 23(x + 250)
Answer:
(2) 23x + 250
Step-by-step explanation:
We are given that
Company charges for one-time set up=$250
Charge for each printed jersey=$23
x=Number of jerseys for team
We have to find the expression which represents the total cost of x number of jerseys for the team.
Total cost of x jerseys printing=[tex]23\times x[/tex]
Total cost of x jerseys printing[tex]=23x[/tex]
Therefore,
Total cost of x number of jerseys for the team=250+23x
Hence, option (2) is true.
(2) 23x + 250

BE and CE are twoequal alltitudes of triangle ABC using RHS congurence rule prove that triangle ABC is isoloes
Answer:
The answer is below
Step-by-step explanation:
BE and CF are two equal altitudes of triangle ABC using RHS congruence rule prove that triangle ABC is isosceles.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
The RHS congruence rule states that if the hypotenuse and one leg of one triangle is equal to the hypotenuse and leg of another triangle; then the two triangles are equal. Two triangles are equal if they have three equal angles and three equal sides.
We have right angle triangles BEC and BFC
BE = CF (given)
CB = BC (both triangles have the same hypotenuse)
Hence ΔBEC = ΔBFC (RHS congruence rule)
Therefore; ∠BCE = ∠FBC (congruence theorem)
Since two angles of triangle ABC are equal (∠B = ∠C), therefore triangle ABC is an isosceles triangle and AB = AC

The temperature at 5:30 a.M. Was –4° Fahrenheit (F). Eight hours later, at 2:30 p.M., the temperature is the opposite of –4 °F. What is the temperature at 2:30?
Answer: 4°F
Step-by-step explanation:
From the question, we are informed that temperature at 5:30 a.m was –4°F and that eight hours later, at 2:30 p.m, the temperature is the opposite of –4°F.
The temperature at 2:30 will be 4°F since the opposite of -4 is +4. Also since there's an interval of 8 hours, it's likely that the temperature increased by 1° for every hour. In 8 hours, it'll have increased by 8°, therefore the temperature will then be:
= -4 + 8
= 4°F

Michelle buys a car that costs $15,000. She makes a down payment of $5,000. If she pays $3000 in the next payment, which equation could be used to find the amount she still owes, C, of the car?
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Michelle buys a car that costs $15,000 and that she makes a down payment of $5,000 and later pays $3000 in the next payment.
To get the equation that can be used to find the amount she still owes, C, of the car, we will have to deduct the amount that she has paid from the cost of the car. This will be:
C = 15000 - 5000 - 3000
C = 15000 - 8000
Therefore solving the equation further, the amount left to pay will be:
C = 15000 - 8000
C = 7000
