An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The equation can be used to find the cost of the bracelets.

5x + 22.50 + 150 = 235

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The number of bracelets sold = 5

The number of necklaces sold = 1

Cost of the necklace = $22.50

Cost of the bracelets = x

The amount left = $150

The total amount in the account after selling them = $235

Now,

The equation can be used to find the cost of the bracelets.

5x + 22.50 + 150 = 235

Thus,

The equation can be used to find the cost of the bracelets.

5x + 22.50 + 150 = 235

Answer:

The area of each slice of cake is [tex]\frac{25}{12}\pi\ in^2[/tex]

Step-by-step explanation:

step 1

Find the area of the complete cake

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=10/2=5\ in[/tex] ----> the radius is half the diameter

substitute

[tex]A=\pi (5)^{2}[/tex]

[tex]A=25\pi\ in^2[/tex]

step 2

Find the area of each slice of cake

Remember that the area of complete circle subtends a central angle of 360 degrees

If you cut the cake into 12 equal slices

then

the central angle of each slice is equal to [tex]\frac{360^o}{12}=30^o[/tex]

so

Using proportion

Find out the area of each slice for a central angle of 30 degrees

[tex]\frac{25\pi}{360^o}=\frac{x}{30^o} \\\\x= \frac{25\pi}{360^o}(30^o)\\\\x=\frac{25}{12}\pi\ in^2[/tex]

Note This problem could be solved by directly dividing the area of the circle by 12, however, proportions and concepts of central angle were applied for didactic purposes

Each slice of the 10-inch diameter cake, cut into 12 equal slices, has an area of approximately 6.54 square inches.

To find the area of each slice of the cake, we need to calculate the area of the entire cake first and then divide it by 12 since the cake is divided into 12 equal slices.

The formula for the area of a circle is: Area = πr².

Given the diameter of the cake is 10 inches, we first need to find the radius: radius = diameter / 2 = 10 / 2 = 5 inches.

Now, calculate the area of the entire cake:

Area of the full cake = π × (5 inches)² = 25π square inches.

Since the cake is cut into 12 equal slices, the area of each slice is:

Area of each slice = (25π) / 12 = 25π / 12 ≈ 6.54 square inches.

Therefore, each slice of cake has an area of approximately 6.54 square inches.

Answer:

12 degrees.

Step-by-step explanation:

8 - (-4) = 12. So, the temperature increased by 12 degrees.

The temperature increased by 12 degrees from -4 to 8.

The question is asking for the temperature change from -4 to 8 degrees. To find the increase in temperature, you subtract the initial temperature from the final temperature. In this case, 8 (final temperature) minus (-4) (initial temperature), equals 12°C. Hence, the temperature increased by 12 degrees.

To find the coordinates of the other endpoint B given the midpoint M and one endpoint A. Apply the midpoint formula and solve the equations to find the coordinates of B(-1, 5).

The midpoint coordinates are given as M(3, -2) and one endpoint is given as A(7, -9). To find the coordinates of the other endpoint, we can use the midpoint formula which states that the coordinates of the midpoint are the average of the coordinates of the two endpoints.

Let the coordinates of the other endpoint be B(x, y). Using the midpoint formula, we have:

[(x + 7) / 2, (y + -9) / 2] = (3, -2)

Simplifying the equation, we get:

(x + 7) / 2 = 3

(y - 9) / 2 = -2

Multiplying both sides by 2, we have:

x + 7 = 6

y - 9 = -4

Subtracting 7 from both sides, we get:

x = -1

Subtracting -9 from both sides, we get:

y = 5

Therefore, the coordinates of the other endpoint are B(-1, 5).

Each computer costs $225 and each printer costs $150

Step-by-step explanation:

Thomas is starting a new company. He has two quotes from a computer company for the cost of computers and printers

We need to find how much each computer and printer costs

Assume that the cost of each computer is $x and the cost of each printer is $y

∵ The cost of each computer is $x

∵ The cost of each printer is $y

∵ The cost of 3 computers and one printer is $825

- Multiply x by 3 and add the product to y, equate the sum by 825

∴ 3x + y = 825 ⇒ (1)

∵ The cost of 4 computers and 2 printers is $1200

- Add the product of 4, x and the product of 2 , y and equate the

  sum by 1200

∴ 4x + 2y = 1200 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -2 to eliminate y

∵ -6x - 2y = -1650 ⇒ (3)

- Add equations (2) and (3)

∴ -2x = -450

- Divide both sides by -2

∴ x = 225

Substitute the value of x in equation (1) to find y

∵ 3(225) + y = 825

∴ 675 + y = 825

- Subtract 675 from both sides

∴ y = 150

Each computer costs $225 and each printer costs $150

By setting up a system of equations from the scenarios provided, we can determine that each computer costs $225 and each printer costs $150.

To determine the cost of each computer and printer, we can set up a system of equations based on the information provided. Let C represent the cost of one computer and P represent the cost of one printer. Using the first scenario where three computers and one printer cost $825, we can write the first equation as:

3C + P = $825 ... (1)

For the second scenario where four computers and two printers cost $1200, we can write the second equation as:

4C + 2P = $1200 ... (2)

Next, we'll solve this system of equations using either substitution or elimination method. To use elimination, we can multiply equation (1) by 2 to eliminate the printers:

6C + 2P = $1650 ... (3)

Now, we subtract equation (2) from equation (3) to find C:

6C + 2P - (4C + 2P) = $1650 - $1200

2C = $450

C = $225

We now know each computer costs $225. To find the cost of a printer, we can replace C in either equation (1) or (2). Let's use equation (1):

3(225) + P = $825

675 + P = $825

P = $825 - 675

P = $150

Thus, each computer costs $225 and each printer costs $150.

Answer:

f(x) = (2x + 1)(2x − 1)

Explanation:

As we can see from the above function f(x) = 4[tex]x^{2}[/tex] − 1, we need to find x-intercept, i.e., the value of x where this function's value is zero.

So let us Equate the function with zero

4[tex]x^{2}[/tex] - 1 = 0 => 4[tex]x^{2}[/tex] = 1 => [tex]x^{2}[/tex] = 1/4 => x = [tex]\sqrt{1/4}[/tex]

Hence we get 2 values of x, i.e., +1/2, and -1/2.

So now we need to check out the functions which are zero at this values of x, so let us substitute values of x in each and every option and see the values of functions.

Option A - f(x) = (4x + 1)(4x − 1) = 3, -3

Option B - f(x) = (2x + 1)(2x − 1)  = 0

Option C - f(x) = 4(x2 + 1)  = 5

Option D - f(x) = 2(x2 − 1) = -3/2

Hence answer is Option B

The taxable amount was $80.86

Step-by-step explanation:

Given,

Sales tax = .07

Total grossed = $1236.00

Let,

x be the price before sales tax, therefore,

Amount of sales tax = 0.07x

Price before sales tax + Sales tax = Total amount grossed

x+0.07x = 1236

1.07x=1236

Dividing both sides by 1.07

[tex]\frac{1.07x}{1.07}=\frac{1236}{1.07}\\x=1155.14[/tex]

Taxable amount = Total amount grossed - Price before tax

Taxable amount = 1236 - 1155.14 = $80.86

To solve for x, first we move 2 to the other side of the equation.

3e^2x = 28-2

3e^2x = 26

Dividing both sides by 3

e^2x = 26/3

e^2x = 8.67

Taking the natural logarithm if both sides

ln(e^2x) = ln8.67

2x = ln8.667

Answer:

x²-9x+12 = (x - (9/2))²- (33/4)

Step-by-step explanation:

Look at the photo below for the details.

:)

In order to find the variables p and q in the equation x^2 - 9x + 12 = (x-p)^2 - q, we first complete the square on the left-hand side which leads us to determine that p=4.5 and q=32.25.

The original equation given is x^2 - 9x + 12 = (x-p)^2 - q. To find the values of p and q, we need to rewrite the left-hand side of the equation in the format of (x-p)^2. This can be done through a process known as completing the square. Looking at the equation x^2 - 9x + 12, we have a perfect square x^2 - 9x + (9/2)^2 = (x-4.5)^2. However, remember, we added (9/2)^2 to both sides, so we have (x-4.5)^2 = x^2 - 9x + 12 + 20.25. Simplifying, (x-4.5)^2 = x^2 - 9x + 32.25, which is our original equation format. Thus, p=4.5 and q=32.25.
