A una obra de teatro acudieron 420 personas y se recaudaron $48,000.00. Si el costo de la entrada de los adultos fue de $200 y el costo de la entrada de niños costaba $80. ¿Cuántos adultos y niños que acudieron?
Answer:
La respuesta es que acudieron 120 adultos y 300 niños.
Step-by-step explanation:
De acuerdo a la información proporcionada, puedes escribir las siguientes ecuaciones:
x+y=420 (1)
200x+80y=48,000 (2), donde:
x es el número de adultos
y es el número de niños
Primero, puedes despejar x en (1):
x=420-y (3)
Ahora, puedes reemplazar (3) en (2):
200(420-y)+80y=48,000
84,000-200y+80y=48,000
84,000-48,000=200y-80y
36,000=120y
y=36,000/120
y=300
Finalmente, puedes reemplazar el valor de y en (3) para encontrar el valor de x:
x=420-y
x=420-300
x=120
De acuerdo a esto, la respuesta es que acudieron 120 adultos y 300 niños.

Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y = m x + b , where m is the slope and b is the y intercept.
y = m x + b
Find the values of m and b using the form y = m x + b .
m =− 5 3 b = 2
The slope of the line is the value of m , and the y-intercept is the value of b .
Slope:
− 5 3
y-intercept: 2

You are running a concession stand at a basketball game. You are selling hotdogs and sodas. Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50. You sold a total of 87 hotdogs and sodas combined. How many hotdogs did you sell?
Answer:
35 hotdogs
Step-by-step explanation:
You are running a concession stand at a basketball game. You are selling hotdogs and sodas.
Let the number of hot dogs be represented by x
The number of soda be represented by y
You sold a total of 87 hotdogs and sodas combined
x + y = 87
x = 87 - y
Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50.
Hence we have the equation:
$1.50 × x + $0.50 × y = $78.50
1.50x + 0.50y = 78.50
Substitute 87 - y for x
1.50(87 - y) + 0.50y = 78.50
130.5 - 1.50y + 0.50y = 78.50
Collect like terms
- 1.50y + 0.50y = 78.50 - 130.50
-1.00y = -52
y = -52/-1
y = 52 sodas
How many hotdogs did you sell?
Using the equation:
x = 87 - y
x = 87 - 52
x = 35 hotdogs
Hence, you sold 35 hotdogs

A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y = -4x2 + 141x – 703
Answer:
b
Step-by-step explanation:
The maximum amount of profit the company can make is $543
Let y represent the amount of profit and x represent the selling price.
The relationship between x and y is:
y = -4x² + 141x – 703
The maximum profit is at dy/dx = 0, hence:
dy/dx = -8x + 141
-8x + 141 = 0
8x = 141
x = 17.625
The maximum profit is:
y = -4(17.625)² + 141(17.625) – 703 = 543
The maximum amount of profit the company can make is $543

Ry=-1(p)
The image is _____?
Answer:
Step-by-step explanation:
y=0,3
x=-4,0
(-4,3)
The required coordinate of the image of p is under y = -1 is given as (-4, 4).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate the y is called ordinate.
Here,
Coordinates of point P = (-4, 3)
Now,
[tex]R_{y = -1}(p)[/tex]
The question of the image is given that
(x, y) ⇒ (x, -[y + 1])
= (-4, -[3 + 1]) = (-4, -4)
Thus, the required coordinate of the image of p is under y = -1 is given as (-4, 4).

Kiran and Clare live 24 miles away they start walking at 8 am Clare is walking 3.4 miles per hour and they get there at 10:30 am how fast was Kiran jogging
Answer:
Kiran is jogging at 9.6 miles per hour.
Step-by-step explanation:
We can find the speed of Kiran as follows:
[tex] v = \frac{x}{t} [/tex]
Where:
v: is the speed =?
x: is the distance = 24 miles
t: is the time
If Clare and Kiran started walking at 8 am and they get to their destination at 10:30 am, then the time is:
[tex] t = 10:30 - 8:00 = (10 h + 30min*\frac{1 h}{60 min}) - 8 h = 2.5 h [/tex]
Then, the speed of Kiran is:
[tex] v = \frac{x}{t} = \frac{24 miles}{2.5 h} = 9.6 miles/h [/tex]
Therefore, Kiran is jogging at 9.6 miles per hour.

Answer:
y = -3x + 7
Step-by-step explanation:
Using any 2 pairs of values, say (-3, 16) and (-1, 10), therefore, rate of change of the data given = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{10 - 16}{-1 -(-3} = \frac{-6}{2} = -3 [/tex].
We would get the same rate of change if we use any other two pairs of values in the data given.
Therefore, the data can be modeled by a linear equation because the rate of change remains constant all through.
To represent y as a function of x, find b, since we know the rate of change (m).
Substitute x = -3, y = 16 and m = -3 in y = mx + b.
Thus:
16 = (-3)(-3) + b
16 = 9 + b
Subtract 9 from each side
16 - 9 = b
7 = b
b = 7
Substitute m = -3 and b = 7 in y = mx + b
The function would be:
✅ y = -3x + 7
