How do you find the answer ?
jeka94
I think first you must Unification of denominatorsit will 60 for (3,4,5) so you will get 
2\5 = 24\60
1\4 = 15\60
1\3 = 20 \60
then you divide each one apart then multiply by total number (3,800)
so :
24\60 * 3800 = 1520
15\60 * 3800 = 950
20 \60 * 3800 = 1267
_____
note : when you will gather results you will get Approximate number to 3800

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night
mario62 [17]

Using proportions, it is found that $1,225 is earned from nachos.

  • This question is solved by <em>proportions</em>, using a rule of three.
  • The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.
  • When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?

The <em>rule of three</em> is:

$1,540 - $1,330

$1,672 - $x

Applying line multiplication:

1672x = 1540 \times 1330

x = \frac{1540 \times 1330}{1672}

x = 1225

$1,225 is earned from nachos.

HELP PLSS <br> Solve the equation 17−(3x+5)=3x−6

Answer:

x = 3

General Formulas and Concepts:

<u>Pre-Algebra</u>

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

17 - (3x + 5) = 3x - 6

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute negative:                   17 - 3x - 5 = 3x - 6
  2. Add 3x on both sides:               17 - 5 = 6x - 6
  3. Combine like terms:                  12 = 6x - 6
  4. Isolate <em>x</em> term:                            18 = 6x
  5. Isolate <em>x</em>:                                     3 = x
  6. Rewrite:                                      x = 3

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    17 - (3(3) + 5) = 3(3) - 6
  2. Multiply:                               17 - (9 + 5) = 9 - 6
  3. Add:                                     17 - 14 = 9 - 6
  4. Subtract:                              3 = 3

Here we see that 3 does indeed equal 3.

∴ x = 3 is the solution to the equation.
