Let
x ----> the amount of pure acid (100% solution) in gallons
Remember that



we know that

solve for x


therefore
3 gallons of pure acid should be mixed with 3 gallons of a 20% acid solution in order to get a 60% acid solution
6x3 +2x2-3x-7 these are supposed to go in the boxes
4
Step-by-step explanation:
