PLEASW HELP/ ILL MARK BRAINLIEST

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.

Answer:

3) 14

Step-by-step explanation:

in the given equation replace the "g(x)" with the provided "20"

20=2(x-4) solve as usual

divide each side by 2

10=x-4

add 4 to each side

14=x

the value of x is 14

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

Answer:

6.66 miles

Step-by-step explanation:

Miles run in 27 minutes = 3 miles

Miles run in 1 minute = 3÷27 miles = [tex]\frac{1}{9}[/tex]

1 hour = 60 minutes

Therefore,

Miles run in 60 minutes = [tex]\frac{1}{9}[/tex] × 60

                                        = [tex]\frac{20}{3}[/tex] miles OR 6.66 miles

Answer:

y = 6x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 6 and given point (0, 4 ) ⇒ c = 4

y = 6x + 4 ← equation of line

it must be less than 41 degrees

We are going to define two equations where b means bagels and m will be muffins, First equation: 10*b + 4*m = 13 Second equation: 5*b + 8*m = 14 From the second equation, we can isolate b: b = (14 - 8*m)/5 In the second equation 10*(14 - 8*m)/5 + 4*m = 13 2*(14 - 8*m) + 4*m = 13 28 - 16*m + 4*m = 13 28 -13 = 16*m - 4*m 15 = 12*m m = 15/12 = 1.25 Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8 So one bagel costs $0.8 and one muffin $1.25

Answer:

Muffins: $1.25

Bagels: $0.80

Answer:

about 0.075

Step-by-step explanation:

The estimation of the quotient 1.64 divided by 22 is 0.0745.

Given that,

Based on the above information, the calculation is as follows:

[tex]= 1.644 \div 22[/tex]

= 0.0745

Therefore we can conclude that the estimation of the quotient 1.64 divided by 22 is 0.0745.

Answer:

(4, 1 )

Step-by-step explanation:

Given the 2 equations

3x + 2y = 14 → (1)

3x - 2y = 10 → (2)

Adding the 2 equations term by term, eliminates y , that is

6x = 24 ( divide both sides by 6 )

x = 4

Substitute x = 4 into either of the 2 equations and solve for y

Substituting into (1)

3(4) + 2y = 14

12 + 2y = 14 ( subtract 12 from both sides )

2y = 2 ( divide both sides by 2 )

y = 1

Solution is (4, 1 )

Answer:

The x-coordinate is -7

Step-by-step explanation:

We can use the internal division formula to find this;

That will be;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

we only need the x coordinates in this case

m = 3 and n = 4

x = 4(-4) + 3(-11)/(3 + 4)

x = (-16 -33)/7 = -49/7 = -7

Answer:

A. -7

Step-by-step explanation: hope this helps :)

When the triangle is reflected across the x-axis, then point B would be (6, -6), but when it's also translated four units to the left, it will be (2, -6).

When you reflect something across an axis, then a point you recall will have the x or y value have the opposite sign (i.e. 6 would become -6 across the x-axis and vice versa).

When you translate something across the graph, you are adding to the x value when shifting to the right, subtracting from the x value when shifting to the left, adding to the y value when shifting upward, and subtracting from the y value when shifting downward.

∴, B = (2, -6).

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
