A stadium charges $75 for each seat in section A, $50 for each seat in section B, and $40 for section C. There are three times as many seats in section B as in section A. The revenue from selling odd 20,000 seats is 897,500. Write a system to represent the situation.
A. b=3×c
a+b+c=20,000
75a+50b+40c=897,500
B. b=3×a
a+b+c=20,000
75a+50b+40c=897,500
C. a=3×b
a+b+c=20,000
40a+50b+75c=897,500
D. a=3×b
a+b+c=20,000
75a+50b+40c=897,500
Answer:
B. b=3×a
a+b+c=20,000
75a+50b+40c=897,500
Step-by-step explanation:
A stadium charges
$75 for each seat in section A
$50 for each seat in section B
$40 for section C.
There are three times as many seats in section B as in section A.
a = 3× b
The revenue from selling odd 20,000 seats is 897,500.
a + b + c = 20,000 seats
Hence,
$75 × a + $50 × b + $40 × c = 897,500
75a + 50b + 40c = 897,500
Hence, the system of equations is :
B. b=3×a
a+b+c=20,000
75a+50b+40c=897,500

1 15/100 + 1/50 + 1.175
Answer:
Step-by-step explanation:
Change fractions to have the same denominator or change them all to a decimal. Then add.
Decimal method:
1 and 15/100 is equal to 1.15
1/50 is equal to 0.02
The final term is already a decimal
Add. 1.15 + 0.02 + 1.175 = 2.345

A circle divided into 4 parts. 2 parts are shaded.
Which fraction is equivalent to One-half? Use the diagram to help answer the question.
One-fourth
Two-fourths
Three-fourths
Four-fourths
A circle is divided into 4 parts out of which 2 parts are shaded. The diagram is attached for a better understanding. The fraction equivalent to 'Half' is 'Two-fourths'.
A fraction is part of the whole. It consists of two parts, that are:
1. Numerator: The number at the top of a fraction is called Numerator.
2. Denominator: The number at the bottom of a fraction is called Denominator.
The 'Half' is written in the number system as [tex]\dfrac{1}{2}[/tex].
Let's multiply the numerator and denominator by 2,
[tex]\dfrac{1}{2}= \dfrac{1 \times 2}{2 \times 2} = \dfrac{2}{4}[/tex]
Hence, the factor 'Two-fourths' is equivalent to 'Half'.

A group of three friends order a combo meal which includes case slices of pizza and a drink each drink is priced at 2:50 if the time and channel is 3150 how much is the cost of a slice of pizza
Given :
A group of three friends order a combo meal which includes case slices of pizza and a drink each drink is priced at $2.50 .
Total bill, T = $31.50 .
To Find :
The cost of a slice of pizza.
Solution :
Price of 3 drinks, P = 3×2.50 = $7.5 .
Now,
[tex]\text{Price of each slice }=\dfrac{\text{Total price - Price of drinks}}{\text{Number of slice}}\\\\p = \$(\dfrac{31.50-7.50}{3})\\\\p = \$8[/tex]
Therefore, price of each slice of pizza is $8.
Hence, this is the required solution.

How do you solve this?
Answer:
[tex] x = 18 [/tex]
[tex] y = 7.5 [/tex]
[tex] z = 7 [/tex]
Step-by-step explanation:
✍️[tex] (8x - 7) + (3x - 11) = 180 [/tex] (consecutive interior angles are supplementary)
Solve for x
[tex] 8x - 7 + 3x - 11 = 180 [/tex]
Add like terms
[tex] 11x - 18 = 180 [/tex]
Add 18 to both sides
[tex] 11x = 180 + 18 [/tex]
[tex] 11x = 198 [/tex]
Divide both sides by 11
✅[tex] x = 18 [/tex]
✍️[tex] (2y + 23) = (4y + 8) [/tex] (alternate interior angles are congruent)
Solve for y
[tex] 2y + 23 = 4y + 8 [/tex]
Collect like terms
[tex] 23 - 8 = 4y - 2y [/tex]
[tex] 15 = 2y [/tex]
Divide both sides by 2
✅y = 7.5
✍️[tex] (2y + 23) + (3z^2 - 5) = 180 [/tex] (linear pair angles)
Plug in the value of y
[tex] (2(7.5) + 23) + (3z^2 - 5) = 180 [/tex]
[tex] (15 + 23) + (3z^2 - 5) = 180 [/tex]
[tex] 38 + 3z^2 - 5 = 180 [/tex]
Add like terms
[tex] 3z^2 + 33 = 180 [/tex]
Subtract 33 from each side
[tex] 3z^2 = 180 - 33 [/tex]
[tex] 3z^2 = 147 [/tex]
Divide both sides by 3
[tex] z^2 = \frac{147}{3} [/tex]
[tex] z^2 = 49 [/tex]
Square both sides
[tex] \sqrt{z^2} = \sqrt{49} [/tex]
[tex] z = 7 [/tex]

Answer:
k = $0.50
Step-by-step explanation:
The data that we have is:
Rocko paid: $12.50 for 25 tickets.
Louisa paid: $17.50 for 35 tickets.
Now, the question asks to find the constant of proportionality.
A proportional relation can be written as:
y = k*x
where k is the constant, and in this case, y is the price and x the number of tickets bought.
Then replacing with the values above, we have:
$12.50 = k*25
then:
k = $12.50/25 = $0.50
And the other data:
$17.50 = k*35
K = $17.50/35 = $0.50
So we have the same k in both cases, this means that the constant of proportionality is k = $0.50
i'm not all too familiar with the constant of proportionality, but both of the situations have a ratio of 0.5/1..
12.50/25 = 0.5/1
17.50/35 = 0.5/1
hopefully this can help you in some way! sorry if it doesn't
Solve for k
p(k + 12) = 8 – 4k
Solve for k:
k = 4 (2 − 3p)/p + 4
Answer:
k = 4(2 - 3p)/(p + 4).
Step-by-step explanation:
p(k + 12) = 8 – 4k
pk + 12p = 8 - 4k
pk + 4k = 8 - 12p
k(p + 4) = 8 - 12p
k = (8 - 12p)/(p + 4)
k = 4(2 - 3p)/(p + 4).
