Answer:

(32/5, -48/5)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

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

Equality Properties

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

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

-4x + 16 = y

2x - 32 = 2y

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                                                                                                  2x - 32 = 2(-4x + 16)
  2. Distribute 2:                                                                                                    2x - 32 = -8x + 32
  3. [Addition Property of Equality] Add 8x on both sides:                                10x - 32 = 32
  4. [Addition Property of Equality] Add 32 on both sides:                                   10x = 64
  5. [Division Property of Equality] Divide 10 on both sides:                               x = 32/5

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                                                                               -4x + 16 = y
  2. Substitute in <em>x</em>:                                                                                                 -4(32/5) + 16 = y
  3. Multiply:                                                                                                           -128/5 + 16 = y
  4. Add:                                                                                                                   -48/5 = y
  5. Rewrite/Rearrange:                                                                                            y = -48/5

NARA [144]

9514 1404 393

Answer:

  10√5

Step-by-step explanation:

The geometric mean of two numbers is the square root of their product.

  m = √(20×25) = √500 = √100 × √5

  m = 10√5

The geometric mean of 20 and 25 is 10√5.

The resulting fractions is 14/15

<h3>Solving equations</h3>

Given the expression shown below;

1/3 +  2/5(2 - 1/2)^2

Solve the expression in bracket

1/3 + 2/5(3/2)^2

1/3 + 2/5(9/4)

Multiply the fractions

1/3 + 18/20

Find the LCM

20+36/60

56/60

28/30

14/15

Hence the resulting fractions is 14/15
