I believe the answer it 2! 50 is 1/5 of 250, 10 is 1/5 of 50, and 2 would be 1/5 of 10! I hope this helps!

What is the y value of the solution to the system of equations given? y=5x-3 3x-2y=27
nignag [31]

Answer:

y = -18

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

Step-by-step explanation:

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

y = 5x - 3

3x - 2y = 27

<u>Step 2: Rewrite systems</u>

  1. Define:                                        3x - 2y = 27
  2. Add 2y on both sides:               3x = 2y + 27
  3. Divide 3 on both sides:              x = 2/3y + 9

<u>Step 3: Redefine</u>

y = 5x - 3

x = 2/3y + 9

<u>Step 4: Solve for </u><em><u>y</u></em>

  1. Substitute in <em>x</em>:                              y = 5(2/3y + 9) - 3
  2. Distribute 5:                                  y = 10/3y + 45 - 3
  3. Combine like terms:                     y = 10/3y + 42
  4. Subtract 10/3y on both sides:      -7/3y = 42
  5. Divide -7/3 on both sides:            y = -18

Find the solution to the following equation by transforming it into a perfect square trinomial.* x2 + 2x = 8
andriy [413]
x^{2} +2x=8 \ add \ 1 \ to \ both \ sides\\&#10;\\&#10; x^{2} +x+8+1 \ in \ the \ left \ side \ you \ find \ a perfect \ square \ trinomial\\&#10;\\&#10;(x+1)^2=9\\&#10;\\&#10;So:\\&#10;\\&#10;x+1=\pm  \sqrt{9}\\&#10;\\&#10;x+1=\pm 3\\&#10;\\&#10; x+1=3 \rightarrow x=2\\&#10;\\&#10;x+1=-3 \rightarrow \x=-4

Someone tell me working out please?
kozerog [31]
So you need to know that
1. 360 degrees=1 full rotation
2. internal angle of a pentagon
3. internal angle of a square

so we know that
internal pentagon angle+internal pentagon angle+internal angle of square+x=360

internal angle of pentagon=54
internal angle of square=90
so now we have
54+54+90+x=360
198+x=360
subtract 198 from boths ides
x=162
answer is x=162 degrees
