Answer:

2) Subtraction Property of Equality Properties

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Addition Property of Equality - Adding on both sides
  • Subtraction Property of Equality - Subtracting on both sides
  • Multiplication Property of Equality - Multiplying on both sides
  • Division Property of Equality - Dividing on both sides
  • Transitive Property - If a = b and b = c, then a = c
  • Symmetric Property - If a = b then b = a

Step-by-step explanation:

<u>Step 1: Define</u>

4m + 1 = 7 → 4m = 6

<u>Step 2: Identify</u>

We see that we <em>subtracted</em> on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.

1. A-Tunes requires a membership fee of $12 a month and $1 for each download.
matrenka [14]
<h3>Answer:</h3>

After 16 downloads the charges will equal each other.

<h3>Step-by-step explanation:</h3>

First set up an equation

x = Downloads

12 + 1x = 5 + 1.5x

Solve

12 + 1x = 5 + 1.5x <- Rewrite your equation

-5          -5            <- Subtract 5 from both sides

 8 + 1x = 1.5x       <- Simplify

      -1x    -1x         <- Subtract 1 from both sides

        8 = 0.5x      <- Simplify

        8 = 1/2x       <- Convert 0.5 to a fraction to make the next step easier

       16 = x            <- Multiply both sides by 2 to divide by

                                 a fraction
