Answer:

$(4x + 8) = (2x + 28) \\ \\ 4x + 8 = 2x + 28 \\ \\ 4x - 2x = 28 - 8 \\ \\ 2x = 20 \\ \\ x = \frac{20}{2} \\ \\ x = 10$

Answer:

x = 10

Step-by-step explanation:

By the Vertical Angles Theorem that states the vertical angles are congruent.

4x+8 = 2x + 28

-8 -8

-----------------------

4x = 2x + 20

-2x -2x

-------------------------

2x = 20

/2 /2

--------------------------

x = 10

Twenty-eight athletes participate in a 100-meter race. The time of each athlete is measured during the qualification round. The

andriy [413]

The average time of the 20 athletes who did not qualify for the final is 11.2 seconds .

<u>Step-by-step explanation:</u>

Here we have , Twenty-eight athletes participate in a 100-meter race. The time of each athlete is measured during the qualification round. The average time is 11 seconds. The 8 athletes with the fastest time qualified for the final. The average time of these 8 athletes is 10.5 seconds. Let's have equations for this:

$\frac{x_1+x_2+.....+x_2_8}{28} = 11$ where $x_1, x_2, ....., x_2_8$ are athletes

⇒ $x_1 + x_2 + .. + x_2_8 = 11(28)= 308$

⇒ $(x_1 + x_2 + .. + x_8 )+ (x_9+x_1_0+...+x_2_8) = 308$

⇒ $(\frac{x_1 + x_2 + .. + x_8}{8} )(8)+ (\frac{x_9+x_1_0+...+x_2_8}{20} )(20) = 308$

⇒ $10.5(8)+m(20) = 308$ , where m is average time of the 20 athletes who did not qualify for the final.

⇒ $84+m(20) = 308$

⇒ $20m= 224$

⇒ $m=11.2$

∴ The average time of the 20 athletes who did not qualify for the final is 11.2 seconds .

Igoryamba

Answer:

$\sqrt{-64}+2=2+8i$

Step-by-step explanation:

$i=\sqrt{-1}\\\\\sqrt{-64}=\sqrt{(64)(-1)}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\ for\ a\geq0\ and\ b\geq0\\\\=\sqrt{64}\cdot\sqrt{-1}=8\cdot i=8i\\\\\text{Therefore:}\\\\\sqrt{-64}+2=8i+2=2+8i$
