Answer:

x = 72

Step-by-step explanation:

$9 + \frac{3}{4} x = \frac{7}{8} x - 10 \\ \frac{3}{4}x - \frac{7}{8} x = - 10 - 9 \\ \frac{6}{8} x - \frac{7}{8} x = - 19 \\ - \frac{1}{8}x = - 19 \\ x = \frac{ - 9}{ - \frac{1}{8} } \\ x = 72$

Jerome is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability tha

alexira [117]

Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.

Event A - get a green or yellow marble
Event B - get a pink marble

Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
$P(A)= \frac{3+4}{3+4+5+8}= \frac{7}{20} 
\\P(B)= \frac{8}{3+4+5+8}= \frac{8}{20} = \frac{2}{5}$

Probability of combined events is
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$

By substitution,

1.5x - 6 = -4.5x + 21

6x = 27

x = 4.5

Hence, y = 1.5(4.5) - 6 = 0.75
