Answer:

See the below part

Step-by-step explanation:

8 - 2x = 5 - 4x

=> 8 - 5 = -4x + 2x

=> 3 = -2x

=> 3/-2 = x

=> -3/2 = x

4 + 3x = 2 - 2x

=> 4 - 2 = -2x - 3x

=> -2 = -5x

=> 2 = 5x

=> 2/5 = x

2(x - 1) + 2(3x - 1) = 0

=> 2x - 2 + 6x - 2 = 0

=> 8x - 4 = 0

=> 8x = 4

=> x = 4/8

=> x = 1/2

If given a radius of 6mm, what is the diameter?

Leviafan [203]

Answer:

If the radius is 6mm, the diameter is 12mm.

If the diameter is 22 ft, the radius is 11 ft.

Step-by-step explanation:

1st one) When you try to find the diameter of any circle, and you already have the radius, you need to multiply it by two (double it)

6 x 2 = 12mm

2nd one) Then to do the opposite, you need to divide the diameter by 2.

22/2 = 11 ft

Hope this helped :)

Which of the following is equal to the rational expression below when x=11?

topjm [15]

Our first expression is equal to zero:
$\frac{x^2-121}{x+11}= \frac{11^2-121}{11+11} = \frac{121-121}{22}=0$
So we simply find the expression that is equal to zero.
The final answer is a.
$x-11=11-11=0$

If angle 2 measures 155 degrees in the image below and what is the measurement of angle 1

Degger [83]

<h2>Answer:</h2>

<em>Angle 1 measures 25 degrees</em>

<h2>Explanation:</h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the diagram shown below. In that figure, we know that:

$\angle 1=? \\ \\ \angle 2=155^{\circ}$

The figure shows that these two angles are supplementary, so they add up to 180 degrees. Therefore:

$\angle 1+\angle 2=180^{\circ} \\ \\ Substituting \ \angle 2=155^{\circ}: \\ \\ \angle 1+155^{\circ}=180^{\circ} \\ \\ \\ Isolating \ \angle 1: \\ \\ \angle 1=180^{\circ}-155^{\circ} \\ \\ \boxed{\angle 1=25^{\circ}}$
