Answer: 46 chairs

Step-by-step explanation:

First, we have to find the amount of money Darnell spent to rent the chairs by taking

500 - 362 = $138

Then take $138 divided by $3 = 46 chairs

So he rent 1 table and 46 chairs

Answer:

let x - chairs

Darnell rents some tables for $362 and some chairs for $3 each for a party. He spends a total of $500.

500 = 362 + 3x

500 - 362 = 3x

138 = 3x

x = 46

500 = 362 + 3(46)

500 = 362 + 138

500 = 500

Therefore, Darnell rents 46 chairs.

Answer:

B

Step-by-step explanation:

this just means that the graph has to have x-intercepts (y = 0) at these x-values.

so, which graph intersects the x-axis at x = -7/3 and x = 1/2 ?

only B does that.

the others have other x-intercept points.

The line passing through point (-5, -6) is y = -2x - 16.

Define Equation of line.

         y - y₁ = m (x - x₁)  

Given point is (-5, -6) and slope is -2.

We know the formula is,

 y - y₁ = m (x - x₁)  

Let, (x₁, y₁) = (-5, -6)

and, m = -2 (slope)

Now, plug in the value

y - (-6) = -2(x - (-5) )

y + 6 = -2(x + 5)

y + 6 = -2x - 10

y = -2x - 10- 6

y = -2x - 16

Hence, the line passing through point (-5, -6) is y = -2x - 16.

A translation occurs whenever an object is transported from one place to another without altering its dimension, form, or orientation.

A translation occurs whenever an object is transported from one place to another without altering its dimension, form, or orientation. We can draw the translation in the coordinate plane if we know which way and how far to move the figure.

The triangle can be translated in the following ways:

Step 1: In the first step, determine the coordinates of each vertex of the triangle.

Step 2: To translate each point, add the horizontal translation value to the x-coordinate of each vertex and the vertical translation value to the y-coordinate of each point. Add a negative number if either the vertical or horizontal translation for these translations is downhill or to the left.

Step 3: Plot the three translated points and draw the triangle by drawing a straight line between each pair of points.

Answer:

Senior citizen ticket: $9

Child ticket: $13

Step-by-step explanation:

This can be solved by creating a system of equations:

[tex]f(x)=7x+5y=128[/tex]

and

[tex]g(x)=8x+10y=202[/tex]

where x is the cost of a senior citizen ticket and y is the cost of a child ticket.

Solve equation 2 for 5y:

[tex]8x+10y=202\\10y=202-8x\\\frac{10y}{x}=\frac{202-8x}{2}\\5y=101-4x[/tex]

Substitute (101-4x) for 5y in equation 1:

[tex]7x+(101-4x)=128\\3x+101=128\\(3x+101)-101=(128)-101\\3x=27\\\frac{3x}{3}=\frac{27}{3}\\x=9[/tex]

Substitute 9 for x in equation 2:

[tex]8(9)+10y=202\\72+10y=202\\(72+10y)-72=(202)-72\\10y=130\\\frac{10y}{10}=\frac{130}{10}\\y=13[/tex]

A senior citizen ticket costs $9 and a child's ticket costs $13.

To check these values, insert them into the equations:

[tex]128=7(9)+5(13)\\128=63+65\\128=128[/tex]

and

[tex]202=8(9)+10(13)\\202=72+130\\202=202[/tex]

Answer:

A.

Step-by-step explanation:

Just put the equation 3x+4y≥20 into y=mx+b form. Subtract 3x from both sides so you get 4y ≥ -3x+20

then divide everything by 4 to isolate the y.

You would get y ≥ -3/4+ 5. Then just use the slope and y-intercept to graph.

If ≥ symbol is used, shade above the line.

What do you mean by section?

A section is a part or component that, when combined with the other components, forms the total. like the rhythm section of the band that is reviewed in the arts section of a newspaper.

According to the given question,

We have the given information:

A 900 car parking lot is divided into 3 sections. There are 330 spots in Section 1. Section 2 holds 160 more than the amount of cars in Section 3.

Firstly,

900 - 330 = 570 (spots in section 2 and 3)

Secondly,

There are x spots in section 3 and (x + 160) spots in section 2.

So we have :

x + x + 160 = 570

2x = 410

x = 205

Step-by-step explanation:

The Slope is rise/run or (y2 - y1) / (x2 - x1)

We see the y increase by 3 and the x increase by 13, so the slope is

m = 3/13

Answer:

Step-by-step explanation:

To find the slope of the line that passes through the points (-4,5) and (9,8), we can use the formula for slope:

slope = (y2 - y1) / (x2 - x1)

= (8 - 5) / (9 - (-4))

= 3 / 13

= 0.231

Therefore, the slope of the line that passes through the points (-4,5) and (9,8) is 0.231.

The number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

To solve this problem, you can set up a system of equations to represent the given information. The first equation represents the fact that the company uses 138 pounds of peanuts for every 2/3 pound of raisins:

138 pounds peanuts / 2/3 pound raisins = x pounds peanuts

The second equation represents the fact that the company makes 245 pounds of trail mix using only peanuts and raisins:

x pounds peanuts + y pounds raisins = 245 pounds trail mix

To solve for the number of pounds of peanuts used, you can substitute the first equation into the second equation:

(138 pounds peanuts / 2/3 pound raisins) + y pounds raisins = 245 pounds trail mix

Multiplying both sides of the equation by 2/3 to eliminate the fraction, we get:

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds trail mix)

Combining like terms, we get:

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds)

Simplifying the right side of the equation, we get:

138 pounds peanuts + (2/3)y pounds raisins = 160 pounds

Subtracting 138 pounds from both sides of the equation, we get:

(2/3)y pounds raisins = 160 pounds - 138 pounds

Simplifying the right side of the equation, we get:

(2/3)y pounds raisins = 22 pounds

Dividing both sides of the equation by 2/3, we get:

y pounds raisins = (3/2)(22 pounds)

Simplifying the right side of the equation, we get:

y pounds raisins = 33 pounds

Substituting this value into the first equation, we get:

138 pounds peanuts / 2/3 pound raisins = 33 pounds raisins

Multiplying both sides of the equation by 2/3, we get:

138 pounds peanuts / (2/3)(33 pounds raisins) = 33 pounds raisins

Simplifying the right side of the equation, we get:

138 pounds peanuts / 22 pounds raisins = 33 pounds raisins

Dividing both sides of the equation by 22 pounds raisins, we get:

138 pounds peanuts / 22 pounds raisins / 33 pounds raisins = 33 pounds raisins / 22 pounds raisins

Simplifying the equation, we get:

6 pounds peanuts / 1 pound raisins = 33 pounds raisins / 22 pounds raisins

This equation shows that for every 1 pound of raisins the company uses, they use 6 pounds of peanuts.

Therefore, the number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

(138 pounds peanuts / 2/3 pound raisins) + y pounds raisins = 245 pounds trail mix

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds trail mix)

138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds)

138 pounds peanuts + (2/3)y pounds raisins = 160 pounds

(2/3)y pounds raisins = 160 pounds - 138 pounds

(2/3)y pounds raisins = 22 pounds

y pounds raisins = (3/2)(22 pounds)

y pounds raisins = 33 pounds

138 pounds peanuts / 2/3 pound raisins = 33 pounds raisins

138 pounds peanuts / (2/3)(33 pounds raisins) = 33 pounds raisins

138 pounds peanuts / 22 pounds raisins = 33 pounds raisins

138 pounds peanuts / 22 pounds raisins / 33 pounds raisins = 33 pounds raisins / 22 pounds raisins

6 pounds peanuts / 1 pound raisins = 33 pounds raisins / 22 pounds raisins

Therefore, the number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

Step-by-step explanation:

To find the maximum area of one plot, we need to find the greatest common factor of 840 and 396. One way to do this is to use the prime factorization method.

First, we prime factorize 840 and 396:

840 = 2 * 2 * 2 * 3 * 5 * 7

396 = 2 * 2 * 3 * 3 * 11

Then, we find the common factors:

2 * 2 * 3 = 12

So, the greatest common factor of 840 and 396 is 12.

The maximum area of one plot is therefore (840 * 396) / 12 = 140 * 33 = 4620 square meters.
