Value of x for 12(x-2)+3x=1/2(x+6)+2​
Damm [24]

Answer:

The value of x = 2

Step-by-step explanation:

Given the equation

12\left(x-2\right)+3x=\frac{1}{2}\left(x+6\right)+2

  • Expand 12(x-2) = 12x - 24
  • Expand 1/2(x+6) = 1/2x + 3

so the equation becomes

12x-24+3x=\frac{1}{2}x+3+2

simplifying

15x-24=\frac{1}{2}x+5

15x=\frac{1}{2}x+29

multiplying both sides by 2

30x = x + 58

subtracting x from both sides

30x - x = 58 - x

29x = 58

divide both sides by 29

\frac{29x}{29}=\frac{58}{29}

simplifying

x = 2

Therefore, the value of x = 2

Reflections, rotations, and translations are types of transformations. A reflection flips an image, a rotation spins an image, a
Ostrovityanka [42]

Answer:

Hey there!

A "flip" can be considered a reflection.

A "spin" is a rotation.

A "slide" is a translation.

None of these transformations change the way a shape looks, or the size of the shape. They only change how the shape is oriented.

Let me know if this helps :)

Simplify, assume the variable represents a positive real number
kotykmax [81]

The simplification of the given expression \sqrt{18y^{21} will be equal to 3\sqrt{2} (y)^{\dfrac{21}{2}}

<h3>What is simplification?</h3>

The process of reducing the complex mathematical expressions into the simplest form is called as the simplification.

The simplification of the given expression will be:

=\sqrt{18y^{21}}\\\\\\=(18)^{\frac{1}{2} } \times (y)^{\frac{21}{2}}\\\\\\=3\sqrt{2}\times y^{\frac{21}{2}}

hence  the simplification of the given expression \sqrt{18y^{21} will be equal to 3\sqrt{2} (y)^{\dfrac{21}{2}}

Which of the following statements are true of the hypotenuse of a right triangle? Select all that apply. A.) It is the longest s
kirza4 [7]
<span>True    A.) It is the longest side of a right triangle.
False  B.) It is one of the legs. It is opposite the right angle.
False  C.) Its length is the sum of the lengths of the other two sides.
False  D.) It forms a right angle with an adjacent side.

If option B is a single choice, then it has to be called false.

Look at option B.
B. "It is one of the legs" is false.
"It is opposite the right angle" is true.
Are you sure option B. is not two different choices, and there are really 5 choices instead of 4?
