Answer:

\frac{x-4}{5x}

Step-by-step explanation:

The equation;

\frac{x^{2} - 8x + 16}{5x} ÷ x - 4

Factor;

\frac{(x-4)^{2}}{5x} ÷ ( x - 4 )

Rewrite in fraction form, so that one can perform division

\frac{(x-4)^2}{5x} * \frac{1}{x-4}

Simplify, cancel out like terms on opposite sides of the fraction bar

\frac{x-4}{5x}

Heeeeeeeelllllpppp<br>why isnt anyone helping me :(<br>find MK​
Ne4ueva [31]

Answer:

MK=32.5

Step-by-step explanation:

Hey There!

I believe that these triangles are similar

So to find MK we want to find the scale factor

To do this we divide

66/30=2.2

Now we want to divide 72.5 by 2.2

72.5/2.2=32.5

therefore MK=32.5

hope this helps!

There are 60 seats on a train. 6 of the seats are empty. What percentage of the seats on the train are empty?
sergij07 [2.7K]

Answer:

10%

Step-by-step explanation:

  1. Set up a proportion: \frac{6}{60} = \frac{x}{100}  
  2. Cross multiply, then divide: 6 × 100 = 600, 600 ÷ 60 = 10
  3. 10/100 = 10%

I hope this helps!

What is x? I tried it but I don’t think I did it right.
sattari [20]

Answer:

x = 4

Step-by-step explanation:

When a tangent and a secant are drawn from an external point to a circle.

Then the product of the external part of the secant and the entire secant and the square of the measure of the tangent are equal, hence

x(x + 5) = 6²

x² + 5x = 36 ( subtract 36 from both sides )

x² + 5x - 36 = 0 ← in standard form

(x + 9)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 4 = 0 ⇒ x = 4

However, x > 0 ⇒ x = 4
