Answer: \frac{6-x}{x^{2}-2x}

Step-by-step explanation:

Find the least common multiple (LCM) of the denominators. This is:

LCM=x(x-2)

Divide the LCM by each denominator and multiply the result by each numerator, then you obtain:

\frac{2x-3(x-2)}{x(x-2)}

Apply the distributive property, then you obtain:

\frac{2x-3x+6}{x^{2}-2x}

Add like terms, then you obtain:

\frac{6-x}{x^{2}-2x}

<u>Answer:</u>

The correct answer is \frac { 6 - x } { x^2 - 2x }.

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

We are given the following expression and we are to simplify it by finding the difference of these two rational terms:

\frac {2} { x - 2 } - \frac { 3 } { x }

Taking their LCM to get:

\frac { 2x - 3 ( x - 2 )} { x ( x - 2 )}

\frac { 2x - 3x + 6 } { x^2 - 2x }

\frac { -x + 6 } { x^2 - 2x }

\frac { 6 - x } { x^2 - 2x }

Answer:

So you first count how much times the numbers go up,then you add the number you get it is 6+ you add them with 13 and you get 19.

Step-by-step explanation:

So you first count how much times the numbers go up,then you add the numbers so 1 is not enough 2 is not enough 3 is not enough 4 is not enough 5 is not enough 6 is enough, so we add the six with the number that we are adding which is 13,then you get 19

Suppose 6 quarts of a solution that is 52% antifreeze is mixed with 10 quarts of a solution that is 32% antifreeze. (A) how many
Vadim26 [7]
The total amount of the resulting mixture can be calculated by adding up the volume of the given substances assuming that volume addition is applicable given the properties of the fluids used. 

That is,
   T = 6 quarts + 10 quarts = 16 quarts

The total volume of the resulting mixture is 16.

Then, we do the component (antifreeze) balance by adding up the resulting antifreeze from the substances to the total. We let x be the percentage of antifreeze in the final mixture.

    6(0.52) + 10(0.32) = 16(x)

The value of x from the equation is 0.395.

Therefore, the answer to this item is 39.5%.

Compare the fraction 1:24,000 to the fraction 1:3,168,000; which is the largest rational number
gulaghasi [49]

Answer:

\frac{1}{24,000}

Step-by-step explanation:

we know that

When we compare positive fractions with the same numerator, the largest rational number will be the fraction with the lowest denominator

In this problem we have

\frac{1}{24,000}  and   \frac{1}{3,168,000}

Both numerator are equal

Compare the denominators

24,000 < 3,168,000

therefore

\frac{1}{24,000}  is the largest rational number
