How much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 35% antifreeze? to obtain a 35% antifreeze solution, □ gallon(s) of water should be added(simplify your answer.)

1.9 gallon

Step-by-step explanation:

Let 'x' be the amount of water that needed to be added to 1 gallon of pure antifreeze to obtain a solution that is 35% antifreeze.

Total mass of solution = 1+x

Ratio of amount of antifreeze to the total solution :

Ratio of value of antifreeze to the total solution :

The proportion of the amount of antifreeze to the total solution will be :

Hence, the amount of water that is needed to be added =1.9 gallon

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
