Answer:

Cost of one roll of plain wrapping: [tex]\$5[/tex]

Cost of one roll of holiday wrapping paper:  [tex]\$19[/tex]

Step-by-step explanation:

Let be "p" the cost in dollars of one roll of plain wrapping paper and "h" the cost in dollars of one roll of holiday wrapping paper.

Based on the information given, we can set up this system of equations:

[tex]\left \{ {{5p+13h=272} \atop {11p+16h=359}} \right.[/tex]

In order to solve it, we can use the Substitution method. The steps are:

1. Solve for "p" from the first equation:

[tex]5p+13h=272\\\\5p=272-13h\\\\p=\frac{272-13h}{5}[/tex]

2. Substitute the above into the second equation and solve for "h":

[tex]11(\frac{272-13h}{5})+16h=359\\\\598.4-28.6h+16h=359\\\\-12.6h=359-598.4\\\\h=\frac{-239.4}{-12.6}\\\\h=19[/tex]

3. Substitute the value of "h" into [tex]p=\frac{272-13h}{5}[/tex]:

[tex]p=\frac{272-13(19)}{5}\\\\p=5[/tex]

Using root properties and complex numbers, it is found that the equivalent expression is:

[tex]6i\sqrt{3}[/tex]

----------------------------------

The most widely used definition in complex numbers is:

[tex]i^2 = -1 \rightarrow \sqrt{-1} = i[/tex]

The expression is:

[tex]2\sqrt{-27} = 2\sqrt{3 \times -9} = 2\sqrt{3 \times 9 \times -1}[/tex]

Applying the property:

[tex]2\sqrt{3 \times 9 \times -1} = 2\sqrt{3}\sqrt{9}\sqrt{-1} = 6i\sqrt{3}[/tex]

[tex]6i\sqrt{3}[/tex] is the equivalent expression.

Answer:

There is not much that can be done to figure out how to write 0.1875 as a fraction, except to literally use what the decimal portion of your number, the .1875 , means. Since there are 5 digits in 1875 , the very last digit is the "100000th" decimal place. So we can just say that .1875 is the same as 1875/100000.

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> the price of the shirt

y ---> he price of the pants

we have that

The price of three shirts plus the price of two paints must be equal to $300

so

[tex]3x+2y=300[/tex]

This is the equation of the line in standard form

Convert to slope intercept form

[tex]y=mx+b[/tex]

Isolate the variable y

[tex]3x+2y=300[/tex]

subtract 3x both sides

[tex]3x+2y-3x=-3x+300[/tex]

[tex]2y=-3x+300[/tex]

Divide by 2 both sides

[tex]y=-1.5x+150[/tex] ----> equation of the line in slope intercept form

Find out the x-intercept

Remember that the x-intercept is the value of x when the value of y is equal to zero

In this problem, the x-intercept is the price of the shirt when the price of the paints is equal to zero

Using the Standard Form, identify the x-intercept of the graph

The standard form is

[tex]Ax+By=C[/tex]

The x-intercept is C/A

we have

[tex]3x+2y=300[/tex]

so

[tex]300/3=100[/tex]

The x-intercept is the point (100,0)

That means---> The price of the shirt is $100 when the price of the paints is equal to $0

Alternative method to find out the x-intercept (equation in slope intercept form)

[tex]y=-1.5x+150[/tex]

For y=0

[tex]0=-1.5x+150[/tex]

solve for x

[tex]1.5x=150[/tex]

[tex]x=\$100[/tex]

The x-intercept is the point (100,0)

Step-by-step explanation:

Kim is 16 and her sis is 8 because 8+8 equals 16 and 8+16 equals 24

The expression 28(15+9) can be simplified and rewritten using the distributive property as Option D. 28 x 15 + 28 x 9. This is the correct equivalent expression.

To determine which expression is equivalent to 28(15+9), we should first simplify the expression inside the parentheses:

Step 1: Simplify inside the parentheses: 15 + 9 = 24.

Step 2: Multiply by 28: 28 x 24.

Now, let's break it down further:

Using distributive property: 28(15+9) can be rewritten as 28 x 15 + 28 x 9, which will result in distributive multiplication.

Therefore, the equivalent expression is Option D.  28 x 15 + 28 x 9.

x = 13

13 is the first number

the 2nd number is 3 let than twice the first so we create and solve a new equation:

2x - 3 = ?

2(13) = ? substitute 13 from the

34,879 × 10 = 348,790

Step-by-step explanation:

The answer is 348,790 because 34,879 multipled by 10 is 348,790 as shown in the picture above ^^

Answer:

348790

Step-by-step explanation:

According to the Power of 10 rule, whenever you divide by 10 [⅒], you move the decimal mark to the left each time, and of course, whenever you multiply by 10, you move the decimal mark to the right each time. In this case, the decimal mark is just after the 2, so multiplying by 10 will add a zero to the number, making it 348790 [three forty-eight thousand, eight hundred seventy-nine].

Answer:

32%

Step-by-step explanation:

We have been given that your target number of calories is 1700 per day to lose weight, but you are consuming 2500 calories per day.

First of all, we will find number of calories you should eat to lose weight by subtracting 1700 calories from 2500 calories.

[tex]2500-1700=800[/tex]

Now, we will find 800 is what percent of 2500.

[tex]\frac{800}{2500}\times 100=0.32\times100=32\%[/tex]

Therefore, your target should be consume 32% of the calories, you are consuming.

Substitute the given values for y and z into the expression

Answer:30

Step-by-step explanation:2x5+4x5=30

This is tricky because it has a lot of variables, but we just have to treat this problem normally.

[tex]yp+yn=x[/tex]

separate y from p + n (feel free to check that you can do this by multiplying y out again and seeing that we have the same thing as before)

[tex]y(p+n)=x[/tex]

divide p + n on both sides

[tex]y = \frac{x}{p+n}[/tex]

Answer:

[tex]y = \frac{x}{p+n}[/tex]

To solve the equation yp + yn = x for y, factor out y to get y(p + n) = x, then divide both sides by (p + n) to isolate y, resulting in y = x / (p + n).

To solve the equation yp + yn = x for y, you need to factor y out of the left side of the equation.

This gives you y(p + n) = x.

To isolate y, you then divide both sides of the equation by (p + n), assuming p + n
eq 0, to get y = x / (p + n).

I am joyous to assist you anytime.

Answer:

Step-by-step explanation: To find the area of the pyramid shown, we can first start by finding the area of the base. To find the area of the base, we can multiply the length by the width. Notice that both the length and the width of a square are equal so the area of a square will be equal to the length of a side multiplied by the length of a side.

Area = Length x Width = (side) (side)

Area = Side²

(4 cm²) = 16 cm².

Therefore, the area of the bases is 16 cm².

Answer:

It's 100x bigger.

Step-by-step explanation:

I divided 400 by 4 and got 100.

To check the work, you multiply 100 by 4.

The number 400 is 100 times greater than 4 when we divide the number 400 by 4.

The fraction is defined as the division of the whole part into an equal number of parts. The fraction is defined as the representation of one number with respect to the other number. or one number is how many times the other number.

Given numbers are 400 and 4. To calculate the times divide the number 400 by 4. The division will be done as below:-

Divison = 400 / 4

Division = 100

Therefore, the number 400 is 100 times greater than 4.

Answer:

A = 3244

B = 864

C = 3080

Step-by-step explanation:

 700 + a = 3944

 -700          -700

a = 3244

 3944 - b = c - 80 = 3000

c - 80 = 3000

  +80       +80

c = 3080

3944 - b = c ---> 3944 - b = 3080

                          -3944        -3944

                               -b = -864 --->  [tex]\frac{-b}{-1} = \frac{-864}{-1}[/tex]

The solution to the system of equations is:

a= 2380,

b= 864

c= 3080

The given equations are:

1. [tex]\(700 + a = 3944 - b\)[/tex]

2. [tex]\(3944 - b = c - 80\)[/tex]

3. [tex]\(c - 80 = 3000\)[/tex]

From equation 3, we can solve for [tex]\(c\)[/tex]:

[tex]\[c - 80 = 3000\][/tex]

Adding 80 to both sides:

[tex]\[c = 3080\][/tex]

Now, substituting this value of [tex]\(c\)[/tex] into equation 2:

[tex]\[3944 - b = 3080\][/tex]

Solving for [tex]\(b\)[/tex] :

[tex]\[b = 3944 - 3080\]\\b = 864\][/tex]

Finally, substituting the values of [tex]\(b\)[/tex] and [tex]\(c\)[/tex]  into equation 1:

[tex]\[700 + a = 3944 - 864\]\\700 + a = 3080\][/tex]

Solving for [tex]\(a\)[/tex]:

[tex]\[a = 3080 - 700\]\\a = 2380\][/tex]

So the solutions for the variables are [tex]\(a = 2380\), \(b = 864\), and \(c = 3080\)[/tex].

Step-by-step explanation:

We are given the following information in the question.

The x-coordinate changes from -21 to-16. Thus its value increases 5 units.

The y -coordinate changes from -9 to -13. Thus, it decreases by a value of 4 units.

So to obtain the coordinates in the box:

x-coordinate

We decrease 5 units from -21 that is -21 - 5 = -26

y- coordinate

We add 4 units to -9 that is -9 + 4 = -5
