Which oddered pair is the the system of equation?
Mnenie [13.5K]

Answer:

(3, -9)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

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

-5x - 3y = 12

y = x - 12

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                              -5x - 3(x - 12) = 12
  2. Distribute -3:                                 -5x - 3x + 36 = 12
  3. Combine like terms:                     -8x + 36 = 12
  4. Isolate <em>x</em> term:                               -8x = -24
  5. Isolate <em>x</em>:                                        x = 3

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

  1. Define original equation:                    y = x - 12
  2. Substitute in <em>x</em>:                                     y = 3 - 12
  3. Subtract:                                               y = -9

<u>Step 4: Graph systems</u>

Craig just finished reading 120 pages of his history assignment if the assignment is 125 Pages what percent has Craig read so fa
diamong [38]
96% is the answer 100%/x%=125/120
(100/x)*x=(125/120)*x       - we multiply both sides of the equation by x
100=1.04166666667*x       - we divide both sides of the equation by (1.04166666667) to get x
100/1.04166666667=x
96=x
x=96

A washer and a dryer cost $562 combined. The washer costs $88 less than the dryer. What is the cost of the dryer?
Yanka [14]

Answer:

<em>Let the dryer cost x.</em>

<em>Then, the washer costs (x+87)</em>

<em> </em>

<em>Together, they cost  (x) + (x+87) = 787</em>

<em>         2x+87 = 787</em>

<em>            2x = 700           [subtract 97 from both sides]</em>

<em>             x = 350             [divide both sides by 2]</em>

<em> </em>

<em>The dryer cost $350.</em>

<em> </em>

<em>Check:   The washer cost $437.  Together, they cost $787  [good to check, right?]</em>

<em></em>

<em><u>Hope this helps...</u></em>
