I believe that an answer without an explanation is no help.  This answer, however,
is the result of the combination of the seat of my pants and the top of my head,
so I'm afraid that no cogent explanation can be given.  Here's the answer:

adult tickets cost $10 and children's tickets to a show cost $5. if the number of children's tickets was twice the number of adult tickets, how many of each type of tickets was sold if $800 was collcted in tickets sales? ( make sure you write a legend stating what your variable represents)

Answers

x=amount of children tickes sold
y=amount of adult tickets sold

2 times of children as adult
x=2y

total cost is 800
5x+10y=800
divide both sides by 5
x+2y=160
x=2y
2y+2y=160
4y=160
divie by 4
y=40

x=2y
x=2(40)
x=80


80 children tickets
40 adult tickets

Which of the inequalities represents the statement, "two times a number x, less 15, is greater than or equal to 4 times the number y"?

Answers

The choices are:

A) 
2x - 15 ≤ 4y 


B) 
2x - 15 ≥ 4y 


C) 
15 - 2x ≤ 4y 


D) 
15 - 2x ≥ 4y

Therefore, the best and most correct answer among the choices provided by the question is the fourth choice "15 - 2x ≥ 4y". I hope my answer has come to your help. God bless and have a nice day ahead!

we know that

1) The expression "two times a number x, less 15", represent the equation

2x-15

2) The expression "4 times the number y", represent the equation

4y

3) The expression "is greater than or equal to", represent the symbol

\geq

so

4)The complete expression "two times a number x, less 15, is greater than or equal to 4 times the number y", represent the inequality

2x-15\geq 4y

using a graphing tool

see the attached figure

The solution is the shaded area below the full line

The answer is

2x-15\geq 4y

please help :(

Answers


-- The points (0, 2.5) and (4, 2.5) are both 2.5 above the x-axis.

-- The line through them is a horizontal line.   Its equation is  y = 2.5 .

-- Any line perpendicular to it is a vertical line.

-- The vertical line through the point (3, -1) is the line    x = 3 .

Answer:

The answer is D. x = 3

From 19801980 to 20002000, the annual profit of a company was determined by subtracting from \$625{,}000$625,000 the product of \$25{,}000$25,000 and the number of years either before or after 19901990. Which of the following equations below could be used to determine in which year, xx, the profit was \$550{,}000$550,000?a.550−25∣x−1990∣=625
b.625 - 25 | x - 1990 | = 550625−25∣x−1990∣=550
c.625 +25 | x - 1990 | = 550625+25∣x−1990∣=550
d.625 +25 | x + 1990 | = 550625+25∣x+1990∣=550

Answers

Answer: b) 625 - 25 |x - 1990| = 550

Step-by-step explanation:

According to the question,

The annual profit of a company was determined by subtracting from $625,000 the product of $25,000 and the number of years either before or after 1990.

That is, On  x year the total profit is,

P(x) =  625,000 - 25,000 |x - 1990|

But again according to the question,

On x years the profit is $ 550,000

Thus, 625,000 - 25,000 |x - 1990| = 550,000

⇒ 625 - 25 |x - 1990| = 550 ( by dividing both sides by 1000)

Therefore, Option b) is correct.
