Answer:

BC = 84

Step-by-step explanation:

Given

See attachment

Required

Find BC

The sum of angles\ at\ a\ point is 360.

So:

7n + 12 + 13n - 16 + 6n = 360

Collect like terms

7n + 13n + 6n = 360 + 16 - 12

26n = 364

Solve for n

n = 364/26

n = 14

From the circle:

BC = 6n

Substitute 14 for n

BC = 6*14

BC = 84

kvasek [131]

Answer: 1/18

Step-by-step explanation:

9 total marbles

2 red

so the first time he picks it would be a 2/9 chance of the marble being red

the second time there would be 8 total marbles and 2 red, so it would be a 2/8 or 1/4 chance.

the probability is found by doing 2/9*1/4 which equals 2/36 or 1/18.

3x+5=245<br><br> Helpppppppppppp
SOVA2 [1]

<em>Answer:</em>

<em><u>X = 80</u></em>

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

<em>Subtract </em><em>"5"</em><em> from both sides,</em>

<em>3x + 5 - 5 = 245 - 5</em>

<em><u>Simplify,</u></em>

<em>3x = 240</em>

<em><u>Divide both sides by </u></em><em><u>"3"</u></em><em><u>,</u></em>

<em>3x/3 = 240/3</em>

<em>X = </em><em>80</em>


<u><em>Hope this helps :-)</em></u>

Find the constant rate of change for each table
BlackZzzverrR [31]

the constant rate of change, or average rate of change, is just its slope, so we can just pick any two points to get it.


\bf \begin{array}{|cc|ll}\cline{1-2}\stackrel{x}{time}&\stackrel{y}{distance}\\\cline{1-2}1&6\\\underline{2}&\underline{12}\\3&18\\\underline{4}&\underline{24}\\\cline{1-2}\end{array}~\hspace{7em}\begin{array}{llll}(\stackrel{x_1}{2}~,~\stackrel{y_1}{12})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{24})\\\\\\slope =  m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{24-12}{4-2}\\\\\\\cfrac{12}{2}\implies 6\end{array}
