Just by looking at the question x + 6 + 2x = 2x + 6 + 4 so what does x equal and why?

Mathematics

Elis [28]3 years ago

Answer:

x = 4

Step-by-step explanation:

x + 6 +2x = 2x + 6 + 4

combine like terms:

3x + 6 = 2x + 6 + 4

add numbers:

3x + 6 = 2x + 10

subtract 6 on both sides:

3x + 6 - 6 = 2x + 10 - 6

3x = 2x + 4

subtract 2x from both sides:

3x - 2x = 2x - 2x + 4

x = 4

short explanation:

if you look at the equation, both sides have 6 and 2x which would cancel each other out. That would leave x = 4

A regular polygon had n-folds rotation symmetry. how many line of symmetry must it have
VashaNatasha [74]
6.6 Symmetries of Regular Polygons A Solidify Understanding Task A line that reflects a figure onto itself is called a line of symmetry. A figure that can be carried onto itself by a rotation is said to have rotational symmetry. A diagonal of a polygon is any line segment that connects non-consecutive vertices of the polygon. For each of the following regular polygons, describe the rotations and reflections that carry it onto itself: (be as specific as possible in your descriptions, such as specifying the angle of rotation) 1. An equilateral triangle 2. A square 3. A regular pentagon 4. A regular hexagon

A basketball player makes 75% of her free throws. If she made 84 free throws this season, how many has she attempted?
myrzilka [38]
If you would like to know how many free throws did a basketball player attempted, you can calculate this using the following steps:

75% of x is 84
75% * x = 84
75/100 * x = 84
x = 84 * 100 / 75
x = 112 free throws

The correct result would be 1<span>12 free throws.</span>

What is the solution to this system of equations?
antoniya [11.8K]

Answer:

c

Step-by-step explanation:

Since both equations express y in terms of x we can equate the right sides

3x + 5 = - x + 3 ( add x to both sides )

4x + 5 = 3 ( subtract 5 from both sides )

4x = - 2 ( divide both sides by 4 )

x = - 0.5

substitute x = - 0.5 in either of the 2 equations

using y = - x + 3 then y = 0.5 + 3 = 3.5

solution is (- 0.5, 3.5 ) → c

The length of a rectangular is 7/10 ft .and the width is 1/5ft what is the perimeter
Blababa [14]
<h3>Answer:</h3>

\huge\boxed{1 \frac{4}{5}\ \text{ft}}

<h3>Explanation:</h3>

Change \frac{1}{5} so that is has a common denominator.  \frac{1*2}{5*2}=\frac{2}{10}

Make an equation.  \frac{7+7+2+2}{10}

Add.  \frac{14+4}{10}

Add.  \frac{18}{10}

Divide both sides by 2.  \frac{9}{5}

Convert to a mixed number.  1 \frac{4}{5}
