<u>Answer:</u>

The correct answer option is 231 / 703

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

We are given that a jar has 38 marbles, out of which 10 are red, 22 are black and 6 are green. Two marbles are drawn and the first marble is not returned when the second one is drawn.

We are to find the probability that both marbles are black.

1st draw: P (black) = \frac{22}{38} =\frac{11}{19}

2nd draw: P (black) = \frac{21}{37}

P (Both Black) = \frac{11}{19} \times \frac{21}{37} = 231 / 703

Find the value of x in the figure given that SU = 133.<br><br> A) 7<br> B) 9<br> C) 11<br> D) 8
Alekssandra [29.7K]

Answer:

The answer is 9 (B)

Step-by-step explanation:

I got 9 because you have to plug in answer (7, 9, 11, 8) in each equation than add them both together. I first plugged in 7 for x in the equation 9x-5. I got 58. I plugged in 7 for x in the equation 5x+12 and got 47. When I added both the answers together I got 105. The answer was to low because SU has to be 133. I plugged in 9 for x in both equations then added them both and got 133 for SU. I hope this helps.
