A lab group was supposed to make 14 mL of a 36% acid solution by mixing a 20% solution, a 26% solution, and a 42% solution. However, the 20% solution was mislabeled, and was actually a 10% solution, so the lab group ended up with 14 mL of a 34% acid solution, instead. If the augmented matrix that represents the system of equations is given below, what are the volumes of the solutions that should have been mixed? Volume of 20% solution = Ex: 5 # mL Volume of 26% solution = mL Round to the nearest whole number. Volume of 42% solution = ml Show transcribed data Expert Answer 10 This solution was written by a subject matter expert.

However, the 17% solution was mislabeled, and was actually a 7% solution, so the lab group ended up with 9 mL of a 13% acid solution, instead. What are the volumes of the solutions that should have been mixed? Volume of 17% solution 2 mL . Round answers to Volume of 30% solution 2 mL one decimal place. Volume of 40% solution 2 mL . 2
