what number should be placed in the blank to make the equation balanced?
A solution.
When both variables cancel in a linear equation leaving you with a true statement. How should this be interpereted?
It means that whatever you have substituted is the solution of the given linear equation. Or you have substituted the equation in itself.
What is the solution to x2 plus 7x plus 14 equals 0?
You should be able to look at this equation, or use the discriminant and know that there are no real roots.
What is the difference between a number model and a number sentence?
A number sentence has a letter as its solution while a number model has the solution. I remember this by thinking of a number model as a model of what the full equation should be and a number sentence being the opposite of that.

TRUE
According to the problemsolving strategies you've learned so far once you have come up with a solution to the problem you should return to the equation and make sure your answer satisfies it?
true
what number should be placed in the blank to make the equation balanced?
A solution.
What are some steps after coming up with a solution?
If you mean for a math problem, after coming up with a solution you should usually check the solution in the original equation, to be safe.

It means that whatever you have substituted is the solution of the given linear equation. Or you have substituted the equation in itself.
How do you show that a wave function is a solution to the time- independent Schrodinger equation for a simple harmonic oscillator?
To show that a wave function is a solution to the time-independent Schrödinger equation for a simple harmonic oscillator, you substitute the wave function into the Schrödinger equation and simplify. This will involve applying the Hamiltonian operator to the wave function and confirming that it equals a constant times the wave function.
What tasks should you perform if you discover a new problem when testing the solution?
You document the attempted solution You return to the beginning of the troubleshooting process
How do you check your solution with inequalities?
1) Replace the inequality signs in the solution and in the original question with = signs. Substitute the solution inn the question: it should make it true. 2) (Back to the inequalities) Pick another number that satisfies the solution inequality - e.g. if x>2, pick 5. Substitute this into the original inequality: if it makes it true, then you are good to go!
How many gallons of a 10 percent ammonia solution should be mixed with 50 gallons of a 30 percent ammonia solution to make a 15 percent ammonia solution?
Let x represent the gallons of 10% ammonia solution. The total volume of the mixture is x + 50 gallons. The equation for the mixture is: 0.10x + 0.30(50) = 0.15(x + 50). Solving this equation gives x = 50 gallons of the 10% ammonia solution needed.
What is the solution to x2 plus 7x plus 14 equals 0?
You should be able to look at this equation, or use the discriminant and know that there are no real roots.
If conductivity solution is frozen will it change the conductivity?
Conductivity of frozen solution will decrease tremendously, as iones will be immobile in frozen solution. However, upon defrost, the conductivity should return to standard value, if salt has not percititated out of solution irreversibly, which is not ususally the case with conductivity standard solutions.
What is the difference between a number model and a number sentence?
A number sentence has a letter as its solution while a number model has the solution. I remember this by thinking of a number model as a model of what the full equation should be and a number sentence being the opposite of that.
