Answer:

Step-by-step explanation:

convert mixed fractions to improper fractions

rule=a b/c=(ac+b)/c

(1 1/3)/(1 3/4)

(4/3)/(7/4)

rule for dividing fractions=(a/b)/(c/d)=(a/b)(d/c)

(4/3)(4/7) then you can multiply the numerators and denominators

upper layer = 1 ^ 2

second layer = 2 ^ 2

third layer = 3 ^ 2

layer 12 is 12 ^ 2

<u>The formula is: </u>

<u>n * (n + 1) * (2n + 1) / 6 </u>

<u>n = 12 </u>

<u>12 (12 + 1) (2 * 12 + 1) / 6 </u>

<u>12 * 13 * 25/6 = </u>

PLEASE HELP, please write it out in the system of equations (step by step)
gizmo_the_mogwai [7]

Answer:

{x,y}={-2,3}

Step-by-step explanation:

[1]    2x + y = -1

  [2]    x - 2y = -8  <------- given linear equations

Graphic Representation of the Equations : ----> given in attatchment

y + 2x = -1        -2y + x = -8  < ----- point where they connect is shown in graph

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = 2y - 8

// Plug this in for variable  x  in equation [1]

  [1]    2•(2y-8) + y = -1

  [1]    5y = 15

// Solve equation [1] for the variable  y

  [1]    5y = 15

  [1]    y = 3

// By now we know this much :

   x = 2y-8

   y = 3

// Use the  y  value to solve for  x

   x = 2(3)-8 = -2

Solution :

{x,y} = {-2,3}
