Answer:
The probability of choosing bag 1 is 0,0412
Step-by-step explanation:
As the question emphasizes the probability of bag one, it is that we consider only this one. Bag 1 contains 10 blue marbles and 6 red marbles are added, in total 16 marbles. From this bag 1 extract 3 blue and 2 red marbles, without repetition. In probability it is expressed:
P (Bag₁) = 10/16 * * 9/15 * 8/14 * 6/13 * 5/12 = 0,0412
Because the lines are parallel they have the same slope.
Answer is A -3/7
3x-7=5x+19
Add 7 to both sides.
3x=5x+26
Subtract 5x on both sides.
-2x=26
Divide by -2 on both sides.
x=-13
To check the answer you substitute x=-13 back into the equation.
3x-7=5x+19
3(-13)-7=5(-13)+19
-39-7=-65+19
-46=-46
Step-by-step explanation:
We can rewrite the given equation as
As a check, let's multiply out the factors:
and this is our original equation.
