It has infinite solutions so there is no single solution for the first part

6x - 1 = 2x + 5 + 4x - 6

Add same ( right side )

2x + 4x = 6x

5 - 6 = -1

Put that in to the equation

6x - 1 = 6x - 1

Because of this x could be anything since both sides of the equation are the same

6x - 1 = 2x + 5 + 4x - 6

Add same ( right side )

2x + 4x = 6x

5 - 6 = -1

Put that in to the equation

6x - 1 = 6x - 1

Because of this x could be anything since both sides of the equation are the same

What is the value of X?

i think the answer is 8

bc the small one is 4 and the big one is 6

and the other one is 6 so it must be 8

The answer would be 8

in 2020 the attendance at kennedy school's spring festival was 210. in 2021 the attendance was 168. What was tge percent change in the attendance from 2020 to 2022 tound to nearest whole percent

**Step-by-step explanation:**

Total change in number of student = (210 - 168)

=> 42

% change = Change/Original no. of students × 100

=> 42/210 × 100

=> 42/21 × 10

Which pairs of figures are congruent? Which pairs are similar?

**Answer: Look at the explanation**

**Step-by-step explanation: **To understand what figures are congruent and what figures are similar, you need to understand what the terms mean.

Congruent figures have the same shape and size.

Similar figures have the same shape but different size.

The 1st figure is not congruent but it is similar.

2nd figure is congruent and similar which are rectangles. Wheather the figure is rotated or reflected, it is still congruent and similar.

3rd figure is both, congruent and similar which are both triangles.

4th figure is neither. There is a circle and an elipse, which are both round but different shapes.

By knowing the terms congruent and similar, you should have no problem in identifying geometric shapes and sizes.

A bag holding 7 1/5 pounds of mixed nuts will be divided equally among 9 people.

How many pounds of nuts will each person get?

**Answer:**

4/5

**Step-by-step explanation:**

So sorry if im wrong <3

**Answer:**

Each person will get 4/5, or 0.8 pounds of nuts.

**Step-by-step explanation:**

First, we need to convert 7 1/5 into an improper fraction, by multiplying

7 x 5 = 35

and adding

35 + 1 = 36

Our improper fraction is 36/5

Now, we can divide

36 / 9

5 / 1

To do so, we need to switch 9/1 to its reciprocal, 1/9, and then multiply

36 x 1 = 36

5 x 9 = 45

Our answer is 36/45

We can simplify our answer by dividing by 9

36 / 9 = 4

45 / 9 = 5

Our final answer is 4/5, or 0.8 pounds of nuts

**Step-by-step explanation:**

What is the equation y=2x reflected across the y axis

**Answer:**

[tex]y = -2\, x[/tex].

**Step-by-step explanation:**

Find two points on the original line, [tex]y = 2\, x[/tex]:

Setting [tex]x = 0[/tex] gives [tex]y = 0[/tex], which corresponds to the point [tex](0,\, 0)[/tex].

Setting [tex]x = 1[/tex] gives [tex]y = 2[/tex], which corresponds to the point [tex](1,\, 2)[/tex].

Reflect the two points with respect to the [tex]y[/tex]-axis by inverting the [tex]x[/tex]-coordinate of each point. The point [tex](0,\, 0)[/tex] stays the same, whereas the point [tex](1,\, 2)[/tex] would be mapped to [tex](-1,\, 2)[/tex].

Find the equation of the new line. The slope of the new line would be:

[tex]\begin{aligned}\frac{2 - 0}{(-1) - 0} = \frac{2}{(-1)} = -2\end{aligned}[/tex].

Equation of the new line in point-slope form:

[tex]y - 0 = (-2)\, (x - 0)[/tex].

[tex]y = -2\, x[/tex].

Answer:

Step-by-step explanation:

For this question, you need to know several special relationships about circles. A radius goes from the center of a circle to any point on the circle. All the radii (not a typo, plural of radius is radii) are the same size, their measures are equal; we say they are congruent (the symbol is an equal sign with a ~over it)

In the diagram, OA and OB are congruent because they are radii. AC is a tangent, that means that it touches the circle at exactly one point, in this case at A. So since OA is a radius and AC is a tangent, they are perpendicular to each other (makes 90° angles). Then we can subtract 90 - 72 to find the angle OAB. Angle OAB is 14°. In triangle AOB, which has two sides the same, the opposite angles will also be congruent which means OBA is also 14° (OR you could use the exact same logic for OB perpendicular to BC and subtract, same calculation as before) . Once you have the two 14° angles in the triangle, you can use the fact that all the angles in a triangle add up to 180° So then, 14 + 14 + x =180. Solve this equation to find angle AOB. See image.

Six percent of computer chips produced by Cheapo Chips are defective. Each month a random sample of 200 chips manufactured that month are taken. Let X = the number of defective chips in the sample. What are the mean and standard deviation of X?

Using the **binomial distribution**, it is found that the **mean **of X is of **12**, with a **standard deviation** of **3.36.**

For each chip, there are only **two possible outcomes,** either it is defective, or it is not. The probability of a chip being defective is **independent **of any other chip, hence, the** binomial distribution** is used to solve this question.

**Binomial **probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The **mean** of the binomial distribution is:

[tex]E(X) = np[/tex]

The **standard deviation** of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

In this problem:

Then:

[tex]E(X) = np = 200(0.06) = 12[/tex]

[tex]\sqrt{V(X)} = \sqrt{np(1 - p)} = \sqrt{200(0.06)(0.94)} = 3.36[/tex]

The **mean **of X is of **12**, with a **standard deviation** of **3.36.**

**Answer:**

[tex]a_{15}=-268,435,456[/tex]

**Step-by-step explanation:**

First, find what factor each term is multiplied by to get to the next. To do this, divide the second term by the first, the third term by the second, etc

[tex]4\div-1=-4\\-16\div4=-4\\64\div-16=-4[/tex]

The common factor is 4. Using that, you can now write the equation for the geometric sequence in the form of:

[tex]a_n=a_1x^{n-1}[/tex]

It looks scarier than it is. aₙ is the nth term in the sequence, x is the factor, and n is the index in the sequence, that's all it is.

Plug in the information we have to get the equation for this sequence:

[tex]a_n=(-1)(-4)^{n-1}[/tex]

Then, you can solve for the 15th term:

[tex]a_{15}=(-1)(-4)^{15-1}\\a_{15}=(-1)(-4)^{14}\\a_{15}=(-1)(268,435,456)\\a_{15}=-268,435,456[/tex]

Basically, just raise the scale factor to the power of the term you want minus 1, then multiply that by the first number.

Working together, Shawn and Hector can install a tile floor in 6 hours. It would take Shawn 9 hours to do the job alone. What is the value of r, Hectora's rate of work in part per hour?

The **Hectora's rate of work **in part **per hour** is **18 hours**

**Given** the following parameters:

Taking the **sum **of the** reciprocals** of the time taken;

1/6 = 1/9 + 1/r

1/r = 1/6 - 1/9

1/r = 9-6/54

1/r = 3/54

**Cross multiply**

3r = 54

r = 54/3

r = 18 hours
