<h2>Answer:</h2>

n=\frac{25}{2}.

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

\frac{10}{8} =\frac{n}{10}

<h3>2. Solve the equation for n.</h3>

\frac{10}{8} =\frac{n}{10}

10*(\frac{10}{8}) =(\frac{n}{10})*10 ----> Multiply both sides by 10.

10*(\frac{10}{8}) =n----> Simplify.

\frac{10*10}{8} =n----> Solve the fraction product.

\frac{100}{8} =n----> Simplify.

\frac{100/4}{8/4} =n----> Simplify by dividing the numerator and denominator by the       same number.

\frac{25}{2} =n----> Simplify.

n=\frac{25}{2}----> Reorganize.

.

<h3>3. Express your result.</h3>

n=\frac{25}{2}.

<em>Note. </em><em>Check the attched image to see the manual solution of the equation. We took the same steps I explained previously in the manual solution.</em>

The weight of Jane and Jessica was in the ratio of 8 : 9. Jane gained 2 kg while Jessica lost 4 kg. They then had the same weigh
postnew [5]

Answer:

  48 kg

Step-by-step explanation:

The given relations can be used to write a system of equations for the two weights. Those can be solved to find Jane's weight.

__

<h3>setup</h3>

Let x and y represent Jane's and Jessica's original weight, respectively. The ratio of weights was ...

  x/y = 8/9

After the changes in weight, they were equal:

  x+2 = y-4

__

<h3>solution</h3>

Adding 4 to the second equation, we have an expression for y that can be substituted into the first equation.

  y = x +6 . . . . . . . . . . solve the second equation for y

  x/(x+6) = 8/9 . . . . . . substitute for y in the first equation

  9x = 8(x +6) . . . . . . . multiply by 9(x+6)

  x = 48 . . . . . . . . . . . simplify and subtract 8x

Jane weighed 48 kg at first.

_____

<em>Alternate solution</em>

The original difference in "ratio units" was 9-8 = 1 ratio unit. We find that this corresponds to 6 kg after the weight changes make the weights equal. Then 8 ratio units will be 8(6 kg) = 48 kg—Jane's original weight.

(This mental solution is virtually the same as the solution using equations shown above.)

Simplify the expression.<br><br> 6x + 12y + 5 + 2y +8
pogonyaev

Answer:

6x + 14y + 13

Step-by-step explanation:

combine the like terms.

(5+8), (2y + 12y), and 6x which will be dealt with after solving.

13 + 14y + 6x. And that is it because there are no more like terms to be put together.

Kenya Kon sells dishwashers. He earns an 8% commission on sales. How much must be sell in order to earn $3000?
Karolina [17]
Use a variable to solve for this.

x * .08 = 3000

Divide by .08 on both sides.
x = 37500

We can check this by inputting 37500 for x.

37500 * .08 = 3000
3000 = 3000

Kenya Kon must earn $37500 to earn $3000.

The number pi goes on forever with repeating pattern therefore it is irrational
VMariaS [17]
The statement is false. It is incorrect that the number pi is an irrational number because of the phrase in the sentence 'repeating pattern'. Irrational numbers like Pi cannot be expressed as fraction or ratio of integers. Plus, they do not end (or like you said, they go on forever) HOWEVER they do not follow or have a repeating pattern.
