Maria has a bag with 6 red marbles , 6 blue marbles , and 4 green marbles . Without looking Maria pick one marble. She does not
podryga [215]
40%

The probability of her getting a red marble is the number of red marbles divided by the number of total marbles. Since she picked a green marble first, we must subtract one marble from the total number of marbles, so that the total # of marbles is 6 + 6 + 4 = 16 - 1 (green marble) = 15. Since there are 6 red marbles, our probability is 6/15 or 2/5. Converted to percentage form, this is 0.4 —> 40%

Given the system of equations presented here:
Bumek [7]

ANSWER

The correct answer is option B

EXPLANATION


The equations are

3x+5y=29---(1)


and


x+4y=16---(2)


When we multiply the second equation by -3, we obtain;


-3x-12y=-48---(3)


When we combine this new equation with equation (1).


-7y=-19


We can see that x has been eliminated from the equation.


We can then, solve for  y and then substitute the result in to any of the equations to find x.


Hence the correct answer is option B
