Answer:

x = 13

Step-by-step explanation:

6x + 14 + 4x - 8 + 2x + 18 = 180  {Angle sum property of tiangle}

6x + 4x + 2x + 14 - 8 +18 = 180 {Combine like terms}

                         12x + 24 = 180 {Subtract 18 from both sides}

                                  12x = 180 - 24

                                  12x = 156       {Divide both sides by 12}

                                     x = 156/12

x = 13

ANDREA IS A VERY GOOD STUDENT. THE PROBABILITY THAT SHE STUDIES AND PASSES HER MATHEMATICS TEST IS 17/20. IF THE PROBABILITY THA
Eva8 [605]
Let B be the event that Andrea passes her test, and let A be the event 
<span>that she studies. We are given that P(A and B) = 17/20, and that P(A) = 15/16. </span>

<span>Now the probability that Andrea passes her test given that she has studied </span>
<span>is represented by P(BlA). The formula your teacher gave you can be written as </span>
<span>P(BlA) = P(A and B) / P(A). </span>

<span>So P(BlA) = P(A and B) / P(A) = (17/20) / (15/16) = (17/20)*(16/15) = 68/75.</span>

In preparation for the Senior Prom, 8 seniors got together and decided to travel in style and rent a limousine. They investigate
Snowcat [4.5K]
<span>The limousine will cost $240.
$180 for the first three hours, plus 30 for each hour after. They need two extra hours.
So, 180+30(2)=240.
They also want to leave a $20 dollar tip.
So, 240+20=260
That is $260 dollars they need to pay altogether.
Divide that number by the number of students and you'll get how much they each must pay.
260/8=32.50

$32.50 each.
