Solving Rational equations. LCD method. Show work. Image attached.

Answer:

$k=\frac{1}{2}$

Step-by-step explanation:

The given rational equation is

$\frac{5k}{k+2}+\frac{2}{k}=5$

The Least Common Denominator is

$k(k+2)$

Multiply each term by the LCD.

$k(k+2)\times \frac{5k}{k+2}+k(k+2)\times \frac{2}{k}=5k(k+2)$

Simplify;

$k\times \frac{5k}{1}+(k+2)\times \frac{2}{1}=5k(k+2)$

$\Rightarrow k(5k)+2(k+2)=5k(k+2)$

Expand;

$\Rightarrow 5k^2+2k+4=5k^2+10k$

Group similar terms;

$\Rightarrow 5k^2-5k^2+2k-10k=-4$

$\Rightarrow -8k=-4$

Divide by -8.

$k=\frac{1}{2}$

Answer:

<u>So option 4; </u> $\frac{35}{100}$ <u> is the correct option</u>

Step-by-step explanation:

First, we need to convert $\frac{2}{10}$ so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10

$\frac{2}{10} *\frac{10}{10} = \frac{20}{100}$

Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.

$\frac{45}{100} + \frac{20}{100} = \frac{65}{100}$

Now that we have the total distance walked, we need to subtract that to 1 mile. $1mile=\frac{1}{1} = \frac{10}{10} =\frac{100}{100}$

$\frac{100}{100} -\frac{65}{100} = \frac{35}{100}$

So option 4; $\frac{35}{100}$ is the correct option
