The cost of each entity: each pen is $\(1.75\), each folder is $\(2.50\), and each notebook is $\(1.75\).

Let's assign variables to the costs of each supply:

Let the cost of each pen be P dollars.

Let the cost of each folder be F dollars.

Let the cost of each notebook be N dollars.

According to the given information, we can form the following equations:

For Shane:

\(4P + 3F + 2N = 12.25 (Equation \ 1)\)

For Cheryl:

\(4F + 6N = 22 (Equation \ 2)\)

For Isaiah:

\(2P + F + 3N = 10.25 (Equation \ 3)\)

To solve this system of equations, we can use substitution or elimination method.

Using the elimination method, let's multiply Equation 2 by 2 and Equation 3 by 4 to eliminate F:

\(8F + 12N = 44 (Equation \ 4)\\8P + 2F + 12N = 41 (Equation \ 5)\)

Now, subtract Equation 4 from Equation 5 to eliminate F:

\(8P + 2F + 12N - (8F + 12N) = 41 - 44\\8P - 6F = -3\)

Simplifying further, we have:

\(8P - 6F = -3 (Equation \ 6)\)

Now, let's multiply Equation 1 by 4 and Equation 3 by 3 to eliminate N:

\(16P + 12F + 8N = 49 (Equation \ 7)\\6P + 3F + 9N = 30 (Equation \ 8)\)

Now, subtract Equation 8 from Equation 7 to eliminate N:

\(16P + 12F + 8N - (6P + 3F + 9N) = 49 - 30\\10P + 9F - N = 19\)

Simplifying further, we have:

\(10P + 9F - N = 19 (Equation \ 9)\)

Now we have a system of equations consisting of Equation 6, Equation 9, and Equation 2:

\(8P - 6F = -3 (Equation \ 6)\\10P + 9F - N = 19 (Equation \ 9)\\4F + 6N = 22 (Equation \ 2)\)

To find the values of P, F, and N, we can solve this system of equations using any suitable method, such as substitution or elimination.

The fraction that would make the equation true is 2/3.

We are given the equation 4 × ? ? = 6 2 3 2 3 3 3 5 3. To solve the equation 4 × ? ? = 6, we need to find the value of the missing fraction. We can rewrite the equation as 4 × x = 6, where x represents the missing fraction.

To isolate x, we divide both sides of the equation by 4, resulting in x = 6/4. Simplifying the fraction gives x = 3/2. Therefore, the missing fraction that makes the equation true is 3/2, which can also be written as 2/3 in simplified form.

Answer:

7√2

Step-by-step explanation:

i don't feel like explaining

Circle O is represented by the equation (x+7)² + (y + 7)² = 16. The length of the radius of Circle O is 4.

The equation of Circle O, (x+7)² + (y+7)² = 16, is in the standard form of a circle equation: (x - h)² + (y - k)² = r². Comparing it to the given equation, we can determine the values of h, k, and r.

In the given equation:

Center coordinates: (-7, -7) → h = -7, k = -7

Radius squared: 16 → r² = 16

To find the length of the radius, we need to take the square root of r²:

r = √(16)

Calculating the square root, we get:

r = 4

Therefore, the length of the radius of Circle O is 4.

Looking at the answer options, we see that the correct answer is Option B which is equal to 4.

The equation of a circle in the standard form (x - h)² + (y - k)² = r² represents a circle with center (h, k) and radius r. By comparing the given equation to the standard form, we can extract the values of h, k, and r. Taking the square root of r² gives us the length of the radius, which in this case is 4.

I am giving you a hint

sum of all angles in a triangle is 180 degrees use this hint to solve

have a nice day

Answer:

The value of x = 8

Step-by-step explanation:

The sum of angles of a triangle = 180°

=> 65° + 76° + 6x - 9 = 180°

=> 132° +6x = 180

=> 6x = 180 - 132

=> 6x = 48

=> x = 48/6

=> x = 8

and

(6x-9) = 6(8) -9 = 48-9 = 39

Take into account that the formula for the area of a triangle is:

A = b·h/2

where b is the base, h is the height h = 7.2 cm and A is the area A = 28.8 cm²

Solve for b in the previous formula, and replace the values of A and h, as follow:

b = 2·A/h

b = 2(28.8 cm²)/(7.2 cm)

b = 8 cm

Hence, the length of the base of the triangle is 8 cm

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

Answer:

40

Step-by-step explanation:

If a washer and dryer cost $750 and the cost of the washer is two times the cost of the dryer, then the cost of the dryer $250

The total cost of a washer and dryer combined = $750

The cost of the dryer = x

The cost of the washer is two times the cost of the dryer.

The cost of the washer = 2x

Then the equation will be

x + 2x = 750

Add the like terms of the equation

3x = 750

Move 3 to the right hand side of the equation

x = 750/3

x = $250

Hence, if a washer and dryer cost $750 and the cost of the washer is two times the cost of the dryer, then the cost of the dryer $250

The complete question is:

A washer and dryer cost $750 combined the cost of the washer is two times the cost of the dryer what is the cost of the dryer?

The coordinates of Q(6, -4) under a reflection in the x-axis is Q'(6,4)

The coordinates of x will remain the same for reflection in the X axis, while y will change with the opposite sign.

From the question, we have

The coordinates of Q(6, -4) under a reflection in the x-axis is Q'(6,4).

Reflection:

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and shape as the original, but it faces the opposite way. Changes in position during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context. ABC and A'B'C are used to represent the pre-image and image, respectively. The coordinate system may be referred to by the reflection transformation (X and Y-axis).

Therefore , the solution to the given problem of the equation whose factors are (x+2)(x+1)(x+3).

Describe equation.

Two expressions joined by an equal sign form a mathematical statement known as an equation.

An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

According to the Given question:

x³ + 6x² + 11x +6

This pattern of coefficients 1, 6, 11, 6 is actually one that you are likely to encounter frequently.

For demonstration reasons, let's see what occurs if we begin by using the typical technique for resolving a general cubic:

We can use a linear substitution, t = x + b/3a, to simplify any cubic of the form ax3 + bx2 + cx + d, resulting in a cubic in the form a + b + et + f without a quadratic term.

This is the most straightforward type of Tschirnhaus transformation.

In our example, a = 1 and b = 6, so we want t = x + 2.

Note that:

=  + 6+ 12x +8

So we find:

+ 6+ 11x +6 =   − (x + 2)

=  - t

= t ( - 1)

= t(t − 1)(t + 1)

= (x+2)(x+1)(x+3)

Therefore , the solution to the given problem of the equation whose factors are (x+2)(x+1)(x+3).
