We are going to solve the rational equation $\frac{8}{x+ \frac{1}{5} } = \frac{3}{x}$

Step 1. Simplify the denominator of the left hand side of the equation:
$\frac{8}{x+ \frac{1}{5} } = \frac{3}{x}$
$\frac{8}{ \frac{5x+1}{5} } = \frac{3}{x}$
$\frac{40}{5x+1} = \frac{3}{x}$

Step 2. Multiply both sides of the equation by $(5x+1)$ and $x$ :
$\frac{40}{5x+1}(5x+1)(x) = \frac{3}{x}(5x+1)(x)$
$40x=3(5x+1)$
$40x=15x+3$

Step 3. Subtract $15x$ from both sides of the equation:
$40x-15x=15x-15x+3$
$25x=3$

Step 4. Divide both sides of the equation by 25:
$\frac{25x}{25} = \frac{3}{25}$
$x= \frac{3}{25}$

We can conclude that the solution of the rational equation is $x= \frac{3}{25}$

We know that we have to m<span>ake a down payment of $1500 and finance the rest of $20000 at a 1.9% interest rate, making equal monthly payments for 5 years. Our first step to solve this problem would be to convert 5 years into months.

1 year = 12 months

12 * 5 = 60 months

Therefore, in 5 years there are 60 months.

Now lets solve this problem step by step.

Subtract the down payment from $20,000

</span>$20000-$1500=$18500

Multiply the remaining number by the interest rate.

$18500 *1.9 = $35150

Divide 35150 by number of months in 5 years (60)

$35150 / 60 = $585

<span>Therefore, you have to pay $585 per month.</span>

DIA [1.3K]

Answer:the relative ages of the rocks exposed in the circle cliff area are given below.

1. older rocks are exposed in the center and younger rocks in the flanking flatirons.

2. younger rocks are exposed in the center and older rocks in the flanking flatirons.

Step-by-step explanation: this is because whenever older rocks are exposed in circle cliffs, exposure occur at the center while younger rocks will be exposed in the flanking flatirons at this time.

2. But when younger rocks are exposed in contrast to the older rocks, these younger rocks are exposed at the center while the older ones receive exposure at the flanking flatirons.

Note that both cases interchange, exposure of a particular rock occur at the center and the next category of rock receive theirs at flanking flatirons.

If the smallest angle of a triangle is 20° and it is included between sides of 4 and 7, then (to the nearest tenth) the smallest

lawyer [7]

Answer:

$3.5$

Step-by-step explanation:

The smallest side of a triangle is formed by the smallest angle in the triangle.

To find the side opposite (formed by) the 20 degree angle, we can use the Law of Cosines. The Law of Cosines states that for any triangle, $c^2=a^2+b^2-ab\cos \gamma$ , where $a$ , $b$ , and $c$ are the three sides of the triangle and $\gamma$ is the angle opposite to $c$ .
