Step-by-step explanation:

1...... \: let \: the \: percentage \: be \: x \% \\ then \: x \% \: of \: 500 = 375 \\  (\frac{x}{100} )500 = 375 \\ 5x = 375 \\ x =  \frac{375}{5}  \\ \boxed{ x = 75\%} \\  \\ 2.....80\% \: of \: 500 = ( \frac{80}{100} )500 \\ 80\% \: of \: 500 = 80 \times 5 \\ \boxed{ 80\% \: of \: 500 = 40 0}\\  \\ 3.....60\% \: of \: 200 = ( \frac{60}{100} )200 \\ 60\% \: of \: 200 = 60 \times 2\\ \boxed{ 60\% \: of \: 200 = 120} \\ ........his \: statement \: was \: reasonable \: wrong

Answer:

x = 29/6

General Formulas and Concepts:

  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

8x - (2x - 13) = 42

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

  1. [Distributive Property] Distribute negative:                                                     8x - 2x + 13 = 42
  2. [Subtraction] Combine like terms:                                                                    6x + 13 = 42
  3. [Subtraction Property of Equality] Subtract 13 on both sides:                        6x = 29
  4. [Division Property of Equality] Divide 6 on both sides:                                 x = 29/6

<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>:                                                                                                  8(29/6) - [2(29/6) - 13] = 42
  2. Multiply:                                                                                                             116/3 - [29/3 - 13] = 42
  3. [Brackets] Subtract:                                                                                           116/3 - -10/3 = 42
  4. Subtract:                                                                                                            42 = 42

Here we see 42 does indeed equal 42.

∴ x = 29/6 is the solution.
