In problem solving the term rule of thumb refers to?
heuristics
How do you find the solution to a system of equation?
There are several methods. 1. graphing, then find the intersection. 2. Substitution (take one equation and solve for one variable, substitute that into the 2nd equation) 3. Elimination. Arrange both equations in standard form, arrange so that the coefficients on one of the variables are the same and subtract the 2 equations. 4. Cramer's rule, use matrices to solve.
How do you solve the expression 2500x equals 5 please help?
Use the commutative rule in math. If you do something to one side of the equation, you must do the same to the other side. Divide both sides by 2500 to get x = 5/2500, reduce the fraction to get the answer.
How do you solve by Cramer's rule 2x-y 5 x-2y 1?
Oh, what a lovely question! To solve by Cramer's rule, you'll first calculate the determinant of the coefficient matrix, then create matrices by replacing the x-column with the constants and solving for the determinant of that matrix. Finally, you'll divide these determinants to find the values of x and y. Just like painting a happy little tree, take your time and follow each step with care.
Why do two negative numbers add together to make a positive number?
If you do -5+-5 you get -10 which is not a positive number. If you subtract two negative numbers you could get a positive depending on what number you are subtracting. E.G. -5 - -9 =4 which is positive. A good rule a thumb is -- goes up +- goes down.

What is the best definition of heuristic?
A heuristic is a mental shortcut or rule of thumb used to make decisions or solve problems more quickly, although it may not always lead to the most accurate or optimal outcome. Heuristics are commonly used in decision-making when faced with complex or uncertain situations.
