36) The ratio of Slade's stickers to Corbett's stickers is 5: 2. If Corbett
has 27 fewer stickers than Slade, how many stickers do they have
in all?

Respuesta :

Answer: 63 Stickers

Step-by-step explanation:

Given information:

Ratio = Slade : Corbett = 5 : 2

Corbett has 27 fewer stickers

Set variables:

Let x be the number of stickers Corbett has

Let x + 27 be the number of stickers Slade has

Set proportional equation:

[tex]\frac{2}{5}~ =~\frac{x}{x~+~27}[/tex]

Cross multiply the system

[tex]2~(x~+~27)~=~5~*~x[/tex]

Simplify by distributive property

[tex]2~*~x~+~2~*~27~=~5x[/tex]

[tex]2x~+~54~=~5x[/tex]

Subtract 2x on both sides

[tex]2x~+~54~-~2x~=~5x~-~2x[/tex]

[tex]54~=~3x[/tex]

Divide 3 on both sides

[tex]54~/~3~=~3x~/~3[/tex]

[tex]{x=18}[/tex]

Add Corbett's and Slade's amounts together

Corbett = x = 18 stickers

Slade = x + 27 = 18 + 27 = 45 stickers

Total = 18 + 45 = [tex]\Large\boxed{63~Stickers}[/tex]

Hope this helps!! :)

Answer:

63 stickers

Step-by-step explanation:

Define the variables:

  • Let x be the number of stickers Slade had.
  • If Corbett has 27 fewer stickers than Slade:
    ⇒ Corbett = x - 27

Given ratio:

Slade : Corbett = 5 : 2

Substitute the defined variables:

[tex]\implies \sf x : x - 27 = 5 : 2[/tex]

[tex]\implies \sf \dfrac{x}{x-27}=\dfrac{5}{2}[/tex]

Cross multiply:

[tex]\implies \sf 2x=5(x-27)[/tex]

Expand:

[tex]\implies \sf 2x=5x-135[/tex]

Subtract 5x from both sides:

[tex]\implies \sf -3x=-135[/tex]

Multiply both sides by -1:

[tex]\implies \sf 3x=135[/tex]

Divide both sides by 3:

[tex]\implies \sf x=45[/tex]

Therefore, Slade had 45 stickers.

Substitute the found value of x into the expression for the number of stickers Corbett had:

[tex]\implies \sf 45-27=18[/tex]

Therefore, Corbett had 18 stickers.

Total number of stickers = 45 + 18 = 63
