Answer:

153 liters of Petrolyn oil

Step-by-step explanation:

This is a proportion to set this up you do the following:

Nat/Syn = Nat/Syn ; 5/3 = 255/Syn

Then you solve this equation by cross multiplication.

(255*3)/5 = Syn

153 = Synthetic(Petrolyn oil)

If (x, y) is a solution to the system of equations, what is the value of x? 2x + 1/ 2 y = 2 1/ 2 x + 2y = 6
Veseljchak [2.6K]

Answer:

  C) 4/15

Step-by-step explanation:

The two equations ...

  • 2x + 1/2y = 2
  • 1/2x + 2y = 6

can be solved for x using Cramer's rule:

  x = (2·2 -1/2·6)/(2·2 -1/2·1/2) = (4-3)/(4-1/4) = 1/(15/4)

  x = 4/15

_____

Cramer's rule for the solution to ...

  • ax +by = c
  • dx +ey = f

is ...

  • ∆ = ae-db
  • x = (ce -fb)/∆
  • y = (fa-dc)/∆
