A scientist needs 10 liters of a 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the
nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs? Write and solve an equation to match the situation. Equation: [ Select ] Solution: [ Select ] liters of 5% [ Select ] liters of 40%
There will be no points of intersection. Both equations are linear (lines) therefore cannot meet more than once and but since the lines are parallel they will go on forever in the same direction parallel to each other
