Solve the rational equation:. x+3/3x-2 minus x-3/3x+2=44/9x^2-4
NISA [10]
\frac{x+3}{3x-2} - \frac{x-3}{3x+2} = \frac{44}{9x^2-4}
\frac{(x+3)(3x+2) - (x-3)(3x-2)}{(3x-2)(3x+2)} = \frac{44}{(3x+2)(3x-2)}

(x+3)(3x+2) - (x-3)(3x-2) = 44
(3x^2 + 11x + 6) - (3x^2 - 11x + 6) = 44
22x = 44
x = 2Substituting x = 2 into the original does not give any extraneous solutions, so this is the answer.

A bag contains 6 red marbles, 5 blue marbles and 8 green marbles. If three marbles are drawn out of the bag, what is the probabi
SVETLANKA909090 [29]

Answer: 5.8%

Step-by-step explanation:

In this situation there is no replacement so we have to mulitply the probablilty of the first,second, and third marble being green. First marble has a 8/19 probablilty of being selected because 19 total marbles in the bag and 8 green marbles. the next marble will have a 7/18 probabililty because now only 18 marble are in the bag and we are assuming we selected a green marble on our first draw. Same thing with the last green marble it would be 6/17 because there would be 17 marbles in the bag and 6 green ones left assuming we got the first 2

so 8/19*7/18*6/17=

56/969=

0.05779

5.77%

ale4655 [162]

Answer:

231.00

Step-by-step explanation:

Carol earns 16 for 30 minutes, so $32 an hour, 32 * 3 = 96.

Peter earns 15 every 20 minutes, so 20 * 3 = 60 minutes, and 15 * 3 = 45,

so he earns 45 dollars an hour. 45 * 3 = 135

135+96 = 231.00
