Answer:  13

Step-by-step explanation:

10x+8=12x−18

Step 1: Subtract 12x from both sides.

10x+8−12x=12x−18−12x

−2x+8=−18

Step 2: Subtract 8 from both sides.

−2x+8−8=−18−8

−2x=−26

Step 3: Divide both sides by -2.

−2x - 2

=

−26-2

So , x=13

Hoped I helped -

Answer: [tex]x[/tex] = 13

1. 10[tex]x[/tex] + 8 − 12[tex]x[/tex] = 12[tex]x[/tex] − 18 − 12[tex]x[/tex]

  −2[tex]x[/tex] + 8 = −18

2. −2[tex]x[/tex] + 8 − 8 = −18 − 8

   −2[tex]x[/tex] = −26

3. Split both sides by 2.

x = 13

2/6

Step-by-step explanation:

The two points are -3/6 and 5/6. Subtract -3 - 5 and it's 2. 2/6 :)

Answer:

The key to solving two-step equations is identifying the inverse operations that you need to perform. Thinking of an equivalent expression may help you in this process. Also, be sure to go back and check your solution for accuracy.

Example:

Solve: -18 - x = 22.

Do you know what you would have to do to the equation to solve for x?

Solution:

If we think, "-18 - x" is the same as "-x - 18," we can see that x has been multiplied by -1, and, then, 18 has been subtracted from it. To solve for x, we must undo each of these operations. We add 18, and then divide by -1. Now, let's look at the solution to this equation.

-18 - x = 22 • Original equation.

-18 - x + 18 = 22 + 18 • Add 18 to both sides.

-x = 40 • Complete the addition.

[tex]\frac{-x}{1}[/tex]= [tex]\frac{40}{1}[/tex] • Divide both sides by -1.

x = -40 • Complete the division.

Let's check the solution of -40.

-18 - (-40) = 22 • Substitute the value into the equation in parentheses!

-18 + 40 = 22 • Subtracting a negative is the same as adding a positive.

22 = 22 • Complete the addition.

hope this helps!

Answer:

Step-by-step explanation:

Since the number in question is greater than or equal to 1 but less than

10, we can choose any number between 1 and 10, lets take 3 for example.

If we take the product of 3 and an integer power of 10 number without regard to its sign, this can be expressed mathematically as shown;

[tex]3 * 10^{-5}[/tex] where the power of 10 is -5. Note that any  real number can be used as the power since we are not regarding the sign (Here we used -5). The expression formed according to the expression in question is a SCIENTIFIC NOTATION i.e [tex]3 * 10^{-5}[/tex] gives us a scientific notation.

Scientific notation is a means by which we represent very large or small numbers that are difficult to represent using a decimal notation

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2

BD^2 + 25 = 169

BD^2 = 169 - 25 = 144

BD = √144 = 12 :)

Answer:

[tex]18432\,km/h[/tex]

Step-by-step explanation:

Given: A sound wave travels through iron at a rate of [tex]5120\,m/s[/tex]

To find: rate at which the sound wave travel in [tex]km/h[/tex]

Solution:

Use the following units conversions.

[tex]1\,m=\frac{1}{1000}\,km[/tex]

[tex]1\,s=\frac{1}{3600}\,h[/tex]

Now convert [tex]5120\,m/s[/tex] into [tex]km/h[/tex]

Therefore,

[tex]5120\,m/s=(\frac{5120}{1000})(3600)\\ =512(36)\\=18432\,km/h[/tex]

Answer:

x : y = 9 : 13

Step-by-step explanation:

Given that

3x - y : x + 2y = 2 : 5

Express the ratio in fractional form, that is

[tex]\frac{3x-y}{x+2y}[/tex] = [tex]\frac{2}{5}[/tex] ( cross- multiply )

5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )

15x - 5y = 2x + 4y ( subtract 2x from both sides )

13x - 5y = 4y ( add 5y to both sides )

13x = 9y ( divide both sides by 13 )

x = [tex]\frac{9}{13}[/tex] y ( divide both sides by y )

[tex]\frac{x}{y}[/tex] = [tex]\frac{9}{13}[/tex] , that is

x : y = 9 : 13

Answer:

Part-to-part ratios provide the relationship between two distinct groups. For example, the ratio of men to women is 3 to 5, or the solution contains 3 parts water for every 2 parts alcohol.

Part-to-whole ratios provide the relationship between a particular group and the whole populations (including the particular group). For example, 3/5 of the students in the class are girls, or the mixture is 40% rye grass (40% is equivalent to saying 40 of every 100 parts).

Step-by-step explanation:

Answer:

(6,5)

Step-by-step explanation:

The coordinates of point O are (6, 5) if reflects a line such that N is the reflection of B and O is the reflection of C.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Reflects a line such that N is the reflection of B and O is the reflection of C.

From Point C, a vertical line should be drawn downward.

Both of these lines will come together at (6, 5). These will be Point O's coordinates.

Thus, the coordinates of point O are (6, 5) if reflects a line such that N is the reflection of B and O is the reflection of C.
