Write and solve an equation to find the value of the variable 104 137 154 x mean 130?
An equation to find the value of the variable 104, 137, 154 and x with a mean of 130 is: (104 + 137 + 154 + x)/4 = 130 395 + x = 130 * 4 x = 145.
How do you find the value of x in the following 10 times x 73?
You cannot solve an expression. You need an equation or inequality.You cannot solve an expression. You need an equation or inequality.You cannot solve an expression. You need an equation or inequality.You cannot solve an expression. You need an equation or inequality.
How do you find the value of x when there is no equal sign in the equation?
You cannot explicitly find the value of x without an equal sign, as an equation without an equals sign is an algebraic expression. However, we can turn your expression into an equation by adding in an equals sign, but setting the value to a variable. For example, 2x+5=y, or 5x2-4x=y. You can solve for x like that. The phrase "... there is no equal sign in the equation ..." is a meaningless description. Without an 'equal' sign, there is no equation.
How do you solve a simultaneous equation with 3 variables?
You cannot have a simultaneous equation: you must have 2 or more equations for there to be any simultaneity.The simplest method to solve them is to invert the matrix of coefficients but this requires you to know matrix algebra and the question suggests tha you are not that advanced.In that case, express any one of the variables in terms of the other two. Substitute the resulting expression in the other equation(s). Repeat until you have only one variable. Find its value and substitute in the previous equation. That will then enable you to find a second variable. And so on.
Write and solve an equation to find the value of the variable. 5.2 8.3 8.5 7.7 7.8 y mean 7.1?
mean(5.2 + 8.3 + 8.5 + 7.7 + 7.8 + y) = 7.1=> y = 5.1
The process of finding the value of the variable that makes it a true equation is called?
solve
How do you check to see if the value of the variable is a solution to the equation?
Substitute that value in the equation, and then check to see if the resulting statement is TRUE.
How doI solve system of equations by substitution?
Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.
What are the steps to solve a whole number equaiton?
To solve a whole number equation, follow these steps: Simplify both sides of the equation by combining like terms. Use inverse operations to isolate the variable on one side of the equation. Perform the necessary operations to solve for the variable. Check your solution by substituting the value back into the original equation to ensure it satisfies the equation.
How do you solve a equation using unknown variables?
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
How do you solve -12 is less than or equal to -12?
You normally "solve" something when there is a variable involved. In this case there is no variable. All you have to do is decide whether it is true or false. If this is derived from an original equation (or, in this case, inequality) which involved variables, then if the equation (or inequality) without variables is true, it means it is true for ANY value of the variable. If it is false, the original equation (or inequality) can't be satisfied by any value of the variable.
How do you solve the equation 720 equals 2a x 3b x 5c?
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
What should be added to both sides of this equation to solve for the variable a plus 39 equals -60?
-21
Two step equation definition?
A two-step equation is a mathematical equation that requires two steps to solve. It involves applying inverse operations to isolate the variable on one side of the equation. The goal is to determine the value of the variable that satisfies the equation.
How do you solve algebra equations?
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)
What does value of variables mean?
In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
How do you know whether a relation is a function?
Use the definition of a function. If, for any value of one variable, there is only a single possible value of the second variable, then the second variable is a function of the first variable. The second variable is often called the "dependent variable". If you can solve an equation explicitly for the dependent variable, then it is a function. If you can NOT solve it for a variable, it may or may not be a function - it turns out that some equations are hard or impossible to solve explicitly for one of the variables.
