**Answer 1**

The **factors** which can represent the **length** and **width** of the container are; **2x − 1** and **x + 3**.

The **Volume** of a rectangular prism is a three-dimensional quantity and is the product of its **length**, **width** and **height**.

In essence;

Volume = l × w × h.

However, **V** = *2x3 + 5x2 − 3x* and height, **h** = **x**.

Therefore; V/h = l × w

l × w = (2x³ + 5x² - 3x)/x

l × w = 2x² + 5x -3.

l × w = (2x − 1) (x + 3)

Consequently, the **factors** which can represent the **length** and **width** of the container are; **2x − 1** and **x + 3****.**

Calculate the % loss

Cost price of an article =$28

Selling price of the article=$21

### Answers

The % loss of your problem is 25%

The loss in **percentage** is 25%.

Given that,

**Cost** price of an article = $28

Selling price of the article = $21

We know that,

A figure or** ratio **that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should **divide** it by its entirety and then **multiply **it by 100.

The **proportion** therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Now loss can be calculated by **subtracting **selling price from cost price,

Therefore,

28 - 21 = 7

Hence there are loss of $7 in business,

Now to calculate **percentage** loss,

**Divide** loss by cost price then multiply with 100,

Then,

⇒ (7/28)x100

⇒ 25%

**Answer:**

**Step-by-step explanation:**

You are being asked to draw the reflection of the triangle DKW.

As with a reflection in a mirror, the reflected object appears to be as far behind the mirror as the original object is in front of the mirror.

When you reflect a point across a line, the image is as far from the line on the other side as the original point is from the line. When the line of reflection is a vertical line, as here (x = 0 = y-axis), the y-coordinates are unchanged.

Points W and K are 2 units to the right of the y-axis. Their reflections will lie on the same horizontal line, but will be 2 units to the left of the y-axis.

Point D is 5 units to the right of the y-axis, so its reflection will be 5 units to the left.

__

*Additional comment*

The original triangle and its reflection are symmetrical about the line of reflection.

red = 25

25/100 = 1/4

The required **empirical probability **is 1/4 which gets the color of red P(R).

The **probability **is defined as the possibility of an event being equal to the ratio of the number of **favorable **outcomes and the total number of **outcomes**.

A spinner has 4 equal sectors colored yellow, blue, green, and red. If in 100 spins we get

28 blue (B), 25 red (R), 29 green (G), and 18 yellow (Y) outcomes

To find the **empirical probability **of getting a red outcome, we need to **divide **the number of red **outcomes **by the total **number **of spins:

P(R) = 25 red outcomes / 100 spins

The way to distribute the eggs at the lowest cost would be using **5 cartons of 12 eggs and 1 carton of 6 eggs**.

Since Timmy is helping his grandpa on his chicken farm, and he has to pack **66 eggs **into cartons, minimizing the packing cost, and he can use 12-egg cartons and 6-egg cartons, and **two 12-egg cartons cost as much as three 6-egg cartons**, to determine how many cartons of each should be used, the following **calculation** must be performed:

2 x 12 = 3 x 624 = 18Thus, assuming as an example that a total of 2 cartons of 12 eggs and 3 cartons of 6 eggs cost $ 3, the value of each carton would be the following:3/3 = 13/2 = 1.5 66/12 = 5.55 x 1.5 + 1 x 1 = X7.5 + 1 = X8.5 = X

In this way, the way to distribute the eggs at the lowest cost would be using **5 cartons of 12 eggs and 1 carton of 6 eggs**.

Since y is not equal to 10, hence the** coordinate point** does not fall on the line **graph.**

*Since we are not given a graph, we will use the attached graph as a reference:*

The **equation **of a** line **is expressed as y = mx + b

m is the **slope**

b is the **y-intercept**

Get the **slope **of the line

[tex]m = \frac{0-(-2)}{-2-0}\\m=\frac{2}{-2}\\m = 1[/tex]

Since the line suts the y-axis at y = -2, hence b = -2

Get the **equatio**n of the line:

Recall that y = mx + b

y = x + (-2)

y = x - 2

Next is to check if the coordinate (5, 10) lies on the line

If x = 5

y = x - 2

y = 5 - 2

y = 3

Since y is not equal to 10, hence the** coordinate point** does not fall on the line **graph.**

Answer: …….

Explanation: …….

you must use substitution method

x+y=7

2x+y=10

### Answers

**Answer:**

x =** 3, **y =** 4**

**Step-by-step explanation:**

First, set the first equation equal to x. Note the equal sign, what you do to one side, you do to the other.

Subtract y from both sides of the equation:

x + y = 7

x + y (-y) = 7 (-y)

x = 7 - y

Next, plug in 7 - y for x in the second equation:

2x + y = 10

2(7 - y) + y = 10

Simplify. First, distribute 2 to all terms within the parenthesis:

2(7 - y) = (2 * 7) + (2 * -y) = 14 - 2y

Next, combine like terms. Like terms are terms with the same amount of the same variables:

14 - 2y + y = 10

14 (-2y + y) = 10

14 - y = 10

Isolate the variable, y. First, subtract 14 from both sides of the equation:

-y + 14 (-14) = 10 (-14)

-y = 10 - 14

-y = -4

Next, isolate the variable, y, by dividing -1 from both sides of the equation:

(-y)/-1 = (-4)/-1

y = -4/-1 = 4

Next, plug in 4 for y in one fo the given equations:

x + y = 7

x + (4) = 7

Isolate the variable, x. Subtract 4 from both sides of the equation:

x + 4 (-4) = 7 (-4)

x = 7 - 4

x = 3

x =** 3, **y =** 4**

A family has two cars. The first car has a fuel efficiency of 15 miles per gallon of gas and the second has a fuel efficiency of 25 miles per gallon of gas. During one particular week, the two cars went a combined total of 1125 miles, for a total gas consumption of 55 gallons. How many gallons were consumed by each of the two cars that week?

### Answers

**Answer:**

First car consumed 25 gallons

Second car consumed 30 gallons

**Step-by-step explanation:**

Let x = first car gallons

y = second car gallons

15x + 25y = 1125

x + y = 55

Let's use substitution method

Subtract both sides of the bottom equation by y

x + y = 55

- y - y

x = 55 - y

Plug in the new x into the top equation

15(55 - y) + 25y = 1125

825 - 15y + 25y = 1125

10y + 825 = 1125

Subtract 825 from both sides

10y + 825 = 1125

- 825 - 825

10y = 300

Divide by sides by 10

10y/10 = 300/10

y = 30

The second car consumed 30 gallons

Plug in the new y into one of the original equations; let's use the bottom one

x + 30 = 55

- 30 - 30

x = 25

The first car consumed 25 gallons
