-2x -9y = -25
-(-4x -9y =-23)
2x = -2
x = -1

-2(-1) -9y = -25
2 - 9y = -25
-9y = -25 -2
-9y = -27
y = 3
(-1,3)

The following equation is being multiplied by the LCD. Complete the multiplication to eliminate the denominators

frosja888 [35]

Answer:

$(x+2)(x-2) -1(3x)=(x-3)(x-2)$

Step-by-step explanation:

x+2/3x - 1/x-2 = x-3/3x

$\frac{x+2}{3x}-\frac{1}{x-2}=\frac{x-3}{3x}$

LCD is (3x)(x-2). so we multiply the whole equation by LCD

$(3x)(x-2)(\frac{x+2}{3x}-\frac{1}{x-2}=\frac{x-3}{3x})$

We multiply each term by LCD

$(3x)(x-2)(\frac{x+2}{3x})-(3x)(x-2)(\frac{1}{x-2})=(3x)(x-2)(\frac{x-3}{3x})$

$(x+2)(x-2) -1(3x)=(x-3)(x-2)$

Harrizon [31]

Answer:

0.016

Step-by-step explanation:

To find the probability we have to Divide the number of events by the total number of possible outcomes. This will result in the probability of the single event.

Therefore, the formula of probability is

$P(v) = \frac{no of events}{total possible outcomes}\\$

In the given case,

$P(v) = \frac{20}{1250}\\ P(v) = 0.016$

Which is our required answer.
