meaning to evaluate the variable in an expression. An algebraic expression is also a problem that contains no equals sign and you don't solve it, rather you simplify it.It means to solve something.
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
X could be a sign for multiplication, or it could also be a variable. A variable is a letter representing a number.
It is not an equation because there is no equal sign
An equations is a math sentence that asserts the quality of two expressions. Basically it's a math sentence that contains a variable and and equal sign. Is it a problem? Only if you have to solve it! It's easily solved by doing the inverse operation stated with the variable. Ex: n - 32 = 16 To solve you ADD 32 to both sides of the = sign. (to each expression) a - 32 + 32 cancels out so you're left with just "n" = 16 + 32. Add and you get n = 48
Multiply LCD,then do distributive property,subtract number opossite of variable,then divide variable,flip sign if needed, and then simplify....
Square both sides of the equation to get rid of the radical sign. Then just solve as you normally would. Good luck! :-)
In this word problem, think of "is" as an equal sign and "of" as a multiplication sign. "What" would be the variable. Therefore, the problem translated into math is: A = 0.035 x 150000, where 0.035 is the same as 3.5%.
u can't solve it because there has to be one variable to solve and equal sign, ex. 4x=20. U can simifly though distrubute the n to 4 and -x. ur answer is 4n-nx
a variable expression
Without an equality sign the given expression can't be considered to be an equation.
Without an equality sign the given product problem is not an equation.
You can't solve a formula with no equals sign
what is greater than sign
It depends how its used, it could be used as the multiplication sign or it could be used simply as a variable and u need to solve what it is equal to. It has many meanings.
The basic principle of algebra is the equal sign. Whatever you do to one side you must do to the other. Try to rearrange the terms in such a way that you isolate or solve the variable.
That will obviously depend on the specific problem. If you have an equation with a variable under a square root sign, it often helps to square both sides of the equation.
UFA means unrestricted free agent, which means that the player can sign a contract with any team
The main rule is that whatever rule you perform on one side of the equation must also be performed on the other side of the equation. You have to choose the operation in such a way as to isolate the variable you want to solve for.
You can only "solve for n" if you have an equation, i.e. an equal sign - or an inequality.
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
