Solution to Problem 5: The amount of the final mixture is given by 50 ml + 30 ml = 80 ml The amount of alcohol is equal to the amount of alcohol in pure water ( which is 0) plus the amount of alcohol in the 30% solution. Let x be the percentage of alcohol in the final solution. Hence 0 + 30% 50 ml = x (80) Solve for x x = 0.1817 = 18.75%.

6.8 Mixture and Solution Word Problems
6.8 Mixture and Solution Word Problems. Solving mixture problems generally involves solving systems of equations. Mixture problems are ones in which two different solutions are mixed together, resulting in a new, final solution. Using a table will help to set up and solve these problems. The basic structure of this table is shown below: Example ...
Solving Mixture Problems
The amount of alcohol that each part of the mixture adds to the final result is equal to the amount of each solution mixed in, times the fraction of alcohol that that solution is made from. To use this chart to solve the problem, we will use the fourth column as an equation to solve for x. x. The 10 liters of our final mixture must have a total ...
Mixture Word Problems (video lessons, examples and solutions)
Mixture Problems: Example 3: A tank has a capacity of 10 gallons. When it is full, it contains 15% alcohol. How many gallons must be replaced by an 80% alcohol solution to give 10 gallons of 70% solution? Solution: Set up a table for alcohol. The alcohol is replaced: an amount of 15% alcohol is removed and the same amount of 80% alcohol is added.
How do you set up and solve mixture word problems?
mixture. 10. 0.15. 0.15 (10) = 1.5. When the problem is set up like this, we can usually use the last column to write our equation. In this case, the liters of acid within the 10% solution, plus the liters of acid within the 30% solution, must add up to the liters of acid within the 15% solution.
Examples of how to set up & solve mixture problems
You will be mixing a stronger solution with a weaker solution. The number of liters of the stronger solution is currently unknown; I'll use s to stand for the number of liters of the stronger solution. Then the number of liters of the mixture you're making will be s + 50.. Make a table, with the columns showing the numbers of liters of solutions, the percentage of alcohol in each solution ...

System of equations word problem: infinite solutions
The easiest way to deal with it is to eliminate the fractions. You can multiply the 1st equation by 6: 6 (1/6x) - 6 (3y) = 6 (-58) You get: x - 18y = -348. For the 2nd equation, multiply it by 4 to eliminate the fraction. One the fractions are gone, use elimination or substitution to solve the system.

Number of solutions to equations
Let's review the idea of "number of solutions to equations" real quick. Basically, an equation can have: Exactly one solution, like 2x = 6. It solves as x = 3, no other options. No solutions, like x+6 = x+9. This would simplify to 6 = 9, which is, ummm, not true, so no solutions. Infinitely many solutions, such as 3x = 3x.

Creating an equation with infinitely many solutions
1) The variable has one solution. 2) The equation is a contradiction (always false), so it has no solutions. 3) The equation is an identity (always true), so the variable has a solution set of all real numbers. In other words, any number you can imagine will make the equation be true. In this scenario, there are infinite solutions.
Optimal solution of nonlinear 2D variable-order fractional optimal
For the optimal solution of such problems, the optimization method is developed on the basis of operational matrices (OMs) scheme of derivatives, 2D Gauss-Legendre quadrature rule, and Lagrange multiplier technique. The state and control functions are expanded in terms of the GBPs to reduce the complexity of these problems.
