Answer:

x=3

Step-by-step explanation:

How to solve your question

Your question is 1/2(4x-2)=6x-3

Solve

1.Combine multiplied terms into a single fraction

1/2(4x-2)=6x-13

1(4x-2) divided by 2 =6x-13

2.Multiply by 1

3 Subtract 6x from both sides of the equation

4.Simplify

5.Multiply all terms by the same value to eliminate fraction denominators

6.simplify

7.Add 2 to both side of equation

8.Simplify

9.Divide both sides of the equation by the same term

10.Simplify

Step-by-step explanation:

Combine multiplied terms into a single fraction

1/2 (4x-2) / 2 = 6x - 13

1 (4x -2) /2 = 6x -13

Multiply by 1

1 (4x - 2) / 2 = 6x - 2

4x - 2 / 2 = 6x-13

Subtract 6x from both sides of the equation

4x - 2 / 2 = 6x - 3

4x - 2 /2 - 6x =6x -13 -6x

Simplify

Combine like terms

4x -2 /2 -6x = -13

Multiply all terms by the same value to eliminate fraction denominators

4x -2 /2 -6x = -13

2 (4x-2 /2 -6x) =2(-13)

Simplify

Distribute

Cancel multiplied terms that are in the denominator

Combine like terms

Multiply the numbers

-8x -2 = -26

Add 2 to both sides of the equation

-8x -2= -26

-8x -2+2 = -26+2

Simplify

Add the numbers

-8x = -24

Divide both sides of the equation by the same term

-8x = -24

-8x / -8 = -24 / -8

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

Refer to the triangle below. If a = 4 and b = 6, solve for c. show work Also, give the unsimplified radical form answer and then

9966 [12]

Look at the image below where I labeled the sides

To solve this you must use Pythagorean theorem:

$a^{2} +b^{2} =c^{2}$

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 4

b = 6

c = unknown

^^^Plug these numbers into the theorem

$4^{2} +6^{2} =c^{2}$

simplify

16 + 36 = $x^{2}$

52 = $x^{2}$

To remove the square from x take the square root of both sides to get you...

√52 = x

^^^Unsimplified radical

^^^Simplified radical

^^^Rounded to hundedths

If 18 is 45% of value, what is that value

____ [38]

Percent is parts out of 100 so
45%=45/100=9/20
'of' means multiply
18 =9/20 times something
multiply both sides by 20/9 to clear fraction
360/9=something
40=something

the value is 40
