Final answer:

Mrs. Brown spent $8 at the store, which is found by subtracting her remaining amount of $8 from her initial amount of $16.

Explanation:

The amount of money Mrs. Brown spent at the store can be calculated by subtracting the amount she had after shopping from the amount she had before going to the store. Mrs. Brown had $16 before shopping and was left with $8 after shopping. Therefore, to calculate how much money she spent, we would perform the following subtraction:

$16 (before shopping) - $8 (after shopping) = $8 (spent)

Hence, Mrs. Brown spent $8 at the store.

A. X= -9 hope this helps alot

The requried solution of equation 5x + 8 - 3x = -10 is x = -9. Option A is correct.

We can simplify the equation by combining like terms:

5x + 8 - 3x = -10

2x + 8 = -10

2x = -10 - 8

2x = -18

x = -18/2

x = -9

Therefore, the solution to the equation is x = -9.

Hence, the answer is option (A) x= -9.

Melissa and her younger sister are 5 meters apart.

In this scenario, Melissa's younger sister is directly to her right and her older brother is 12 meters directly ahead of her. Since her brother and sister are 13 meters apart, we can use the Pythagorean theorem to find the distance between Melissa and her younger sister.

Let's call the distance between Melissa and her younger sister 'x'. We can set up a right triangle with Melissa, her brother, and her sister as the vertices.

Using the Pythagorean theorem, we have:

x^2 + 12^2 = 13^2

Simplifying the equation, we get:

x^2 + 144 = 169

x^2 = 169 - 144

x^2 = 25

Taking the square root of both sides, we find:

x = 5

Therefore, Melissa and her younger sister are 5 meters apart.

Answer:

k = 5

Step-by-step explanation:

Step 1:  Cross multiply

k/6 = 15/18

k(18) = 6(15)

18k = 90

Step 2:  Divide both sides by 18

18k / 18 = 90 / 18

k = 5

Answer:  k = 5

Another way to do it is to multiply both sides by 6

k/6 * 6 = 15/18 * 6

k = 90 / 18

k = 5

Answer: 5

Step-by-step explanation: To solve for k in the given proportion, we use the means-extremes property. The product of the extremes, (k)(18), equals the product of the means, (6)(15).

So we have (k)(18) or 18k = (6)(15) or 90.

Now we have the equation 18k = 90.

Dividing both sides by 18, k = 5.

It's a good idea to check the answer in these types of problems so if we plug a 5 back in for k in the original proportion, we have [tex]\frac{(5)}{6}= \frac{15}{18}[/tex] which is a true statement since 15/18 reduces to 5/6.

The formula to find density of a sphere is mass/volume.

Density in simple words means the relation between weight and size of a substance. It is basically related to the compactness of a substance.It is a very useful characteristic and every material has density.

To calculate density, we must calculate the mass and volume of the substance.

          p=m/v

where p= density, m= mass of substance, v= volume of substance

Formula to calculate the volume of a sphere = 4/3 [tex]\pi r^{3} \\[/tex]

If you add 3 to x you have [tex]3+x[/tex]

Subtract this from 1: [tex]1-(3+x)=1-3-x=-2-x[/tex]

Double this: [tex]2(-2-x)=-4-2x[/tex]

The required answer is 4 + 2x.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given expression is,

Add 3 to x subtract the result from 1 then double

Convert it to the numerical expression,

Add 3 to x = 3 + x

subtract the result from 1 = 3 + x - 1

⇒ subtract the result from 1 = 2 + x

Now double of result  = 2(2 + x)

⇒ double of result  = 4 + 2x

this is the required solution.

Thus, the required answer is 4 + 2x.

Step-by-step explanation:

To find perimeter, you need to add all the sides of the shape.

The area of a traingle is 1/2 bh.

You must find the "b" in order to find the perimeter.

Example:

A triangle has an area of 18 cm^2.

Therefore, the triangle has a 6 cm base and 6 cm height.

Then multiply the base by three to get 18 cm. That is your perimeter.

Since the answer calls for a decimal, we will convert 1/10 into a decimal, which works out to be 0.1. Now, we multiply 0.1 by 0.08, which results in the decimal place moving one position to the left. Therefore, the answer is *0.008.*

width = 12.1

equation : P = 4w + 4.6

Answer:

The width of the rectangle is 12.1 meters

Step-by-step explanation:

Step 1:  Find the width

2w + 2(w + 2.3) = 53

2w + 2w + 4.6 = 53

Step 2:  Combine like terms

2w + 2w + 4.6 = 53

4w + 4.6 = 53

Step 3:  Subtract 4.6 from both sides

4w + 4.6 - 4.6 = 53 - 4.6

4w = 48.4

Step 4:  Divide both sides by 4

4w / 4 = 48.4 / 4

w = 12.1

Answer:

The original price was $43.50

Step-by-step explanation:

Let

x ----> the original price of a video game

we know that

1) The price of a video game increases by 20%

so

[tex]100\%+20\%=120\%=120/100=1.20[/tex]

The final price is equal to the original price multiplied by 1.20

so

[tex]1.20x[/tex]

2) The price of a video game decreases by 10%

so

[tex]100\%-10\%=90\%=90/100=0.90[/tex]

The final price is equal to the price at this moment multiplied by 0.90

so

[tex]0.90(1.20x)=1.08x[/tex]

Answer:

184.36

Step-by-step explanation:

If you times 40×45=1760 so you have to times 4.19×44= The answer/ 184.36

Deion Sanders would approximately take 3 minutes and 7 seconds to run a mile at his 40 yard dash pace of 4.19 seconds, calculating his speed and using the number of yards in a mile to find the total time needed.

To calculate the time it would take Deion Sanders to run a mile at his 40 yard dash pace, we first determine his speed over that distance. We know he runs 40 yards in 4.19 seconds, so we can calculate his speed as follows:

Speed = distance / time

Speed = 40 yards / 4.19 seconds

Speed  = 9.55 yards/second (approximately)

Since there are 1760 yards in a mile, to find out how long it will take to run a mile, we divide the total yards in a mile by the speed:

Time to run a mile = distance / speed

Time to run a mile = 1760 yards / 9.55 yards/second

Time to run a mile = 184.293 seconds (approximately)

Converting seconds to minutes yields approximately:

184.293 seconds  = 3.07155 minutes (184.293 seconds / 60 seconds per minute)

This result shows that at Deion Sanders' 40 yard dash speed, it would take him approximately 3 minutes and 7 seconds to run a mile.

To calculate the area of the park (rectangle), firstly you are required to do = Length * breadth

So as per the values given in the question, you need to do = [tex](6x+2)(3x+7)[/tex]

After multiplying the above-given values, you will get

= [tex]18 x^2 + 42x + 6x+14 -64[/tex]

https://brainly.com/question/8663941

To calculate the area of the park not occupied by the pond, first compute the total area of the park as (6x + 2)(3x + 7). Then subtract the area of the square pond, 64 sq. ft, to get the final expression for the unoccupied park area: (6x + 2)(3x + 7) - 64.

The subject of this question is Algebra, specifically forming an expression for the area of a rectangle and subtracting the area of a square. First, calculate the total area of the rectangular park. The area of a rectangle is given by the product of its length and width. So, the total area of the park is (6x + 2)(3x + 7).

Second, find the area of the turtle pond. Since it's a square with a side length of 8ft, its area is 8*8 = 64 sq. ft.

Finally, to find the area of the park that is not occupied by the turtle pond, subtract the area of the pond from the total park area. So, the final expression is (6x + 2)(3x + 7) - 64.
