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

Which of the following is the product of the rational expressions shown below? 7x/x-4•x/x+7

LiRa [457]

<h2>The product of the rational expressions $\dfrac{7x}{x-4}.\dfrac{x}{x+7}$ = $\dfrac{7x^2}{x^2+3x-28}$ </h2>

Step-by-step explanation:

We have,

$\dfrac{7x}{x-4}.\dfrac{x}{x+7}$

To find, the product of the rational expressions $\dfrac{7x}{x-4}.\dfrac{x}{x+7}$ = ?

∴ $\dfrac{7x}{x-4}.\dfrac{x}{x+7}$

= $\dfrac{7x.x}{(x-4)(x+7)}$

= $\dfrac{7x^2}{(x(x+7)-4(x+7)}$

= $\dfrac{7x^2}{x^2+7x-4x-28}$

= $\dfrac{7x^2}{x^2+3x-28}$

Thus, the product of the rational expressions $\dfrac{7x}{x-4}.\dfrac{x}{x+7}$ = $\dfrac{7x^2}{x^2+3x-28}$

Answer:

50.24 yd^2

Step-by-step explanation:

The area of a circle can be found using:

$a=\pi r^{2}$

First, we need to find the radius. We have the diameter. The diameter is twice the radius, or

d=2r

We know that the diameter is 8, so we can substitute 8 in for d

8=2r

Since we are trying to find r, we need to get r by itself. To do this, divide both sides by 2.

8/2=2r/2

4=r

Now we know the radius, and can substitute 4 in for r. Also, we can substitute 3.14 in for pi.

$a=\pi r^{2}$

a=3.14*4^2

Solve the exponent

a=3.14*16

Multiply

a=50.24

The area is 50.24 yards^2

Gabriella rented a bike from Jaidee's Bikes. It cost $14 plus $6 per hour. If Gabriella paid $26 total then how many hours did s

RideAnS [48]

Answer:

2 Hours

Step-by-step explanation:

14+6+6 = 26.

You start with 14, and add on 6 which gives you your starting total 20. So that's one hour. then you add another hour, adding on another $6 making the total $26 and two hours of renting time.
