Which system of equations can be used to find the number of liters of 35% acid solution in the mixture?y = x + 18; 0.23y = 0.35x + 4.14y = x + 18; 0.14y = 0.35x + 4.14y = x + 18; 0.35y = 0.23x + 2.52y = x + 18; 0.23y = 0.35x + 2.521 points QUESTION 2Faith mixes 14 liters of 12% acid solution with a 30% acid solution, which results in an 18% acid solution.Let x represent the number of liters of 30% acid 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 30% acid solution in the mixture?y = x + 14; 0.12y = 0.3x + 4.2y = x + 14; 0.18y = 0.3x + 4.2y = x + 14; 0.12y = 0.3x + 1.68y = x + 14; 0.18y = 0.3x + 1.681 points QUESTION 3Marie mixes 16 liters of 78% acid solution with a 25% acid solution to make a 41% acid solution.How many liters of 25% solution did she use?8 liters12 liters13.7 liters37 liters1 points QUESTION 4Marie mixes 16 liters of 18% acid solution with a 27% acid solution to make a 21% acid solution.How many liters of 27% solution did she use?8 liters12 liters13.7 liters16 liters1 points QUESTION 5Faith mixes 14 liters of 12% acid solution with a 30% acid solution to make an 18% acid solution.How many liters of 30% solution did she use?12 liters7 liters21 liters4.7 liters
