one way i solve them is first i add or subtract whatever was done to the constant+variable(4t). then i solve it. after i have solved it i either divide or multioly depending on the sign. i solve the equation after i finished this. i use the calculator to check my answer
here is an example
54x+72/45=12
54x+72/45-72/45=12-72/45
54x=10.4
54x/54=10.4/54
x~0.2
~ this symbol means about
i dont get it,it post to show something like this
x+(-5/4)=-10 1\4?
Word problems require you to slow down, read, and think logically. Many students like to hurry through a test and pick an answer. To work out a word problems, you have to go step-by-step and work toward the end instead of remembering the right answer. Here are some tips: * Write down all information given in the problem. This helps you to look at it more as a math problem and less as a reading assignment. * Work out any math that you know you will need to do. If the question asks for a total, you will need to add; if it asks for a difference, you know you will be subtracting something. If you are not certain what gets added, subtracted, divided, multiplied, etc - wait to think it through! * Put the steps in order based on what the problem says. * Think it through - does it make sense for the steps to be in that order, or do you need to read the problem again? * Work out the final math problem for your solution. * Double-check your math! Example: James has 25 cents more than Tiffany, but 15 cents less than Andrea. If Tiffany has 10 cents, how much money do James and Andrea have? # Information: James = Tiffany + 25; James = Andrea - 15 # You know how much money Tiffany has - you will need to add 25 cents to that and find how much money James has, then add 15 cents to James' money to find Andrea's # It makes sense to start with Tiffany, because you are told how much money she has. You can use that to figure out how much money James has, and can use James' money to figure out Andrea's. # 10 + 25= 35; James has 35 cents; 35 + 15 = 50; Andrea has 50 cents # Double-check: James has 25 cents more than Tiffany - he has 35 cents and it is 25 cents more than 10 cents - but he has 15 cents less than Andrea - he has 35 cents and it is 15 cents less than 50 cents
It depends on the edition, but typically, it would include, working with expressions that include variables - for example, adding, subtracting, multiplying, and dividing such expressions; fractions (also with expressions); writing equations (based on word problems) and solving those equations; factoring polynomials; graphing; perhaps some basic trigonometry. - High school algebra is all about working with variables.
When solving an equation, you are looking for a specific answer or answers. However, when solving inequalities, you are only looking for what an answer could be (for example, your answer could be less than 5 or greater than 32).
Mainly, in the case of simple inequalities, you have to remember that when multiplying or dividing by a negative number, the direction of the inequality changes, for example, from greater-than to less-than or vice versa. Also, for more complicated inequalities, such as those that involve polynomials or absolute values, additional steps are required.
It is essential to use balanced equations when solving stoichiometric problems because each kind of atom has to be the same on both sides of the equation. The chemical reactions that take place are molar ratios.
Ir is in some people's real life. Example: millions of students that want to pass algebra.
V. A. Morozov has written: 'Regularization methods for ill-posed problems' -- subject(s): Differential equations, Partial, Improperly posed problems, Partial Differential equations 'Methods for solving incorrectly posed problems' -- subject(s): Differential equations, Partial, Improperly posed problems, Partial Differential equations
3 R's stand for Read, Represent, Relate and ESP stands for Equate, Solve, and Prove........ These are the process in solving word problems using equations.
Solving inequalities and equations are the same because both have variables in the equation.
Quadratic equations can be used in solving problems where the formula is given, falling object problems and problems involving geometric shapes.All types of engineering professions use the quadratic formula since it applies to ordinary differential equations.
Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable. Solving Two Step Equations Involving Fractions This video explains how to solve two step equations involving fractions.
