Plzzz ! marie mixes 16 liters of 18% acid solution with a 27% acid solution, which results in 21% acid solution. let x represent the number of liters of 27% solution used and let y represent the number of liters of mixture. which system of equations can be used to find the number of liters of 27% acid solution in the mixture? 1. y = x + 16; 0.27y = 0.21x + 2.88 2. y = x + 16; 0.21y = 0.27x + 2.88 3.y = x + 16; 0.21y = 0.27x + 4.32 4. y = x + 16; 0.27y + 2.88x = 0.21

2. y = x + 16; 0.21y = 0.27x + 2.88

Step-by-step explanation:

You have two conditions:

For the first condition,

16 + x = y     Transpose

(1)    y = x + 16

For the second condition

  V₁c₁    +  V₂c₂  =  V₃c₃

16×0.18 + 0.27x = 0.21y

   2.88 + 0.27x = 0.21y               Transpose

(2)           0.21y = 0.27x + 2.88

The system of equations is y = x + 16; 0.21y = 0.27x + 2.88

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
