The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. Find the number.
Monica [59]

Equation to find number: \frac{1}{n} - 3 = \frac{20}{n}

Number's value: n = -\frac{19}{3}



Step-by-step explanation:

Let n be the unknown number.

The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be \frac{1}{n}.

The difference of three and the reciprocal of a number (\frac{1}{n}) would be \frac{1}{n} - 3.

The quotient of 20 and the number (n) would be \frac{20}{n}.

So, with this information we've gathered so far, we can come up with an equation to find what the number equals.

Equation: \frac{1}{n} - 3 = \frac{20}{n}

To find what the number equals we must solve the equation.

X=1/16y^2 the directrix of the parabola is
yan [13]
To solve this problem you must apply the proccedure shown below:

 1. You have the following equation of a parabola, given in the problem above:

 x<span>=1/16y^2

 2. Then, based on the graph attached, you have:

 p=y^2/4x
 p=8^2/(4)(4)
 p=64/16
 p=4

 3. The directrix is:

 directrix=h-p
 directrix=0-4
 directrix=-4

 The answer is:-4</span>

[(4x + 15) / 5x)] = 1/2
Arada [10]
One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:

<span>[(4x + 15) / 5x)] = 1/2  could be written as:

4x + 15        1
----------- =  ---
     5x           2

Then 8x + 30 = 5x

3x = -30,  and so     x = -10 (answer).  Be certain to check this answer through substitution!
