Answer to 9:

  1. Make your denominators the same. Since 9 goes into 54 6 times, multiply the numerator and denominator of -1/9 by 6. \frac{-6}{54} =\frac{-1}{9}
  2. Add numerators together. \frac{9}{54} +\frac{-6}{54} = \frac{3}{54}
  3. Reduce and your answer should be 1/18

Answer to 10:

  1. Find the LCM (least common multiple), which is 36.
  2. Multiply the numerator and denominator from 6/12 by 3 to get it to have a similar denominator as the second fraction.
  3. Multiply numerator and denominator from -4/9 by 4 to get to same denominator as the first fraction.
  4. Add the fractions together and reduce. \frac{18}{36}+\frac{-16}{36}=\frac{2}{36}=\frac{1}{18}
  5. Your answer should be 1/18.

9. 1/18

10. 1/18

<u>Here is how I got my answer for 9:</u>

Step 1: Simply 9/54 to 1/6. Which leaves us with 1/6 - 1/9

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator. By multiplying 6*3 and 9*2. Which leaves us with 3/18 - 2/18.

Step 4: Subtract 3 and two, giving you your answer: 1/18

<u>Here is how I got my answer for 10:</u>

Step 1: Simplify 6/12 to 1/2. Which leaves us with 1/2 - 4/9

Step 2: Find the least common denominator, which is 18.

Step 3: Make the denominators the same as the least common denominator by multiplying 2*9 and 9*2. Which leaves us with 9/18 - 8/18.

Step 4: Subtract 9 and 8, giving you your answer: 1/18

What is an expression to represent the equation
Tatiana [17]

Answer:

8 + \frac{x}{4}

Step-by-step explanation:

I'm assuming you want an answer to the top section of the question.

We can start with 8.

    8

When a problem asks for the sum, it's looking for addition, so we use the + sign.

    8 +

The problem says "a number," so let's represent that with x. Basically, x just means a number we don't know.

    8 + x

The "number" is divided by 4, so we'll just put x/4 as our second term.

   8 + \frac{x}{4}

For the class of 2013's prom Norman's dress shop sold cheaper dresses for $90 each and more expensive dresses for $140 each. The
Tema [17]

Answer:

Number of cheaper dresses sold  is 35

Number of expensive  dresses sold  is 15

Step-by-step explanation:

Given:

Cost of cheaper dresses = $90

Cost of  expensive dresses = $140

Total cost of  the dresses = $5250

To Find:

Number of cheaper dress = ?

Number of expensive  dress = ?

Solution:

Let

The number of  cheaper dresses be x

The number of  expensive dresses be y

(Number of cheaper dresses X cost of cheap dress) +  (Number of Expensive dresses X cost of  expensive dress)  =  $5250

x \times90 +y \times 140 = 5250=  $5250

It is given that the 20 more of the cheaper dresses than the expensive dresses is sold

So,

number of cheaper dress  =  20  +  number of expensive dress

x = 20 + y---------------------------------------(1)

(20+y) \times90 +y \times 140 = 5250 = 5250

(20 \times 90 +y\times 90) +y \times 140= 5250

1800 + 90y+ 140y = 5250

1800 + 230y = 5250

230y =5250 -1800

230y = 3450

y = \frac{3450}{230}

y = 15

Substituting y in (1)

x = 20 +15

x= 35
