Answer:

-3y - 7x - 5

General Formulas and Concepts:

<u>Pre-Algebra</u>

Distributive Property

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

(4y - 3x - 2) - (7y + 4x + 3)

<u>Step 2: Simplify</u>

  1. Distribute negative:                                                                                       4y - 3x - 2 - 7y - 4x - 3
  2. Combine like terms (y):                                                                                 -3y - 3x - 2 - 4x - 3
  3. Combine like terms (x):                                                                                  -3y - 7x - 2 - 3
  4. Combine like terms (Z):                                                                                 -3y - 7x - 5

Use the Pythagorean Theorem:
a^2 + b^2= c^2

a= one side= 68 mi
b= second side= 80 mi
c= hypotenuse= Greenville to Columbia mi


a^2 + b^2= c^2

68^2 + 80^2= c^2
square each number

4,624 + 6,400= c^2

11,024= c^2
take square root of both sides

104.995 mi= c


ANSWER: The distance from Greenville to Columbia is 104.995 miles (rounded to 105 miles).

Hope this helps! :)

6. Complete the two-column proof.
olya-2409 [2.1K]

Answer:

Given: \frac{x}{6} + 2 = 15                             ......[1]

To prove : x =78

Subtraction property states that you subtract the same number to both sides of an equation.

Subtract 2 from both sides of an equation [1];

\frac{x}{6} + 2 - 2= 15 -2

Simplify:

\frac{x}{6} = 13                                             ......[2]

Multiplication property states that you multiply the same number to both sides of an equation.

Multiply 6 to both sides of an equation [2];

\frac{x}{6} \times 6 = 13 \times 6

Simplify:

x = 78                      proved!

Statement                                           Reason

1.  \frac{x}{6} + 2 = 15                 Given

2.  \frac{x}{6} = 13                 Subtraction property of equality

3. x = 78                              Multiplication property of equality
