e and also buy tickets they can use for food or rides. Gwen pays the entry fee and buys 10 tickets. It costs her a total of $30. Tristan pays the entry fee and buys 15 tickets. It costs him a total of $40. Keith pays the entry fee and buys 10 tickets. It costs him a total of $30. In this task, you will create a system of equations and find the cost of each ticket. Let x represent the entry fee and y represent the cost of each ticket in dollars. Write an equation representing how much Gwen paid, Write an equation representing how much Keith paid.
Answers
Answer:
For Gwen:-
x + 10y = 30
x + 15y = 40 - Tristan
if we subtract the above equations:-
we get
5y = 10
y = 2
That is the cost of each ticket is $2.
Step-by-step explanation:

Hello! Can anyone please help me? The topic is angles.
Answers
Answer:
29/4 or 7.25
Step-by-step explanation:
Complimentary angles are two angles that add up to 90
Supplementary angles are two angles that add up to 180
Angle ABC = x
Angle CBD = 7y + 4
Angle DBE = 8y + x
If we can find the measure of angle CBD, then we can find x.
We know that CBD + DBE = 180 because they are supplementary. Therefore...
(7y + 4) + (8y + x) = 180
AND
(7y + 4) + (x) = 90
Now we can use algebra to solve for x and y...
Blah blah blah...
x = 29/4
y = 45/4
3y + 6x + 2x + 7y
simply the given expression
Answers
Answer:
so the answer is 8x+10y
Step-by-step explanation:
since we have to combine like terms like
3y+7y = 10y
and 6x + 2x= 8x

Find AB and M
Answers
Answer:
Step-by-step explanation:
triangle ABC is an equilateral so all angles and sides are equal to each other
AB = 6
triangle DEF is an isosceles so two of its angles are equal to each other
a triangles angles add up to 180°
to find the measure of these angles we’ll write this equation:
x + x + 40 = 180
and solve for x
2x + 40 = 180
2x = 140
x = 70°
so mF is 70°

Answers

Answer:
side lengths are not proportional6, 8, 10Step-by-step explanation:
1. The triangles are not similar because the ratios of side lengths are not the same:
3 : 4 : 5 ≠ 6 : 7 : 8
__
2. We can make the ratios be the same by multiplying the side lengths by a common value, such as 2:
3 : 4 : 5 = 6 : 8 : 10
If triangle B had side lengths of 6, 8, 10, then it would be similar to triangle A.

The function q = 230,000 -28p is a demand function which expresses the quantity demanded of a product q as a function of the price charged for the product p, stated in dollars. Determine the restricted Domain and Range of the function.
Answers
Answer:
D=[0, 8 214.29]
R=[0, 230 000]
Step-by-step explanation:
In order to find the domain, we must think of the least price you can give to the product you are selling. The price cannot be less than zero, since that would mean that you are giving money to the consumer for taking the product away, so zero is the smallest value p can get.
The greatest value the price can get is the one such that the quantity demanded is zero. So we need to determine that price by setting the equation equal to zero and solving for p.
230,000-28p=0
so we get
-28p=-230,000
[tex]p=\frac{-230,000}{-28}[/tex]
so
p=$8,214.29
so the restricted domain for this function would be:
[tex]0\leq p \leq 8,214.29[/tex]
or in interval notation:
D=[0, 8 214.29]
In order to find the range, we just need to determine what's the least and greatest value the function can get. Since this is a linear function, we can find them by just substituting each of the extreme values of the domain in the function, so we get:
q=230,000-28(0)=230,000
q=230,000-28(8214.29)=0
so the range would be:
[tex]0\leq q \leq 230,000[/tex]
or in interval notation:
R=[0, 230 000]

An item cost $450 before tax and the sales tax is $13.50. Find the sales tax rate. Write your answer as a percentage.
Answers
Answer:
3%
Step-by-step explanation:
If an item cost $450 before tax and the sales tax is $13.50 then the sales tax rate is 3%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that An item cost $450 before tax
The sales tax of the item is $13.50
We have to find the sales tax rate in percentage
To find the percentage we have to multiply x/100 with four hundred fifty which is equal to thirteen point five
x/100×450=13.5
4.5x=13.5
Divide both sides by 4.5
x=13.5/4.5
x=3%
Hence, if an item cost $450 before tax and the sales tax is $13.50 then the sales tax rate is 3%.
