57.9 times 0.086 is 4.9794, or 4 and 4897/5000 in fraction form.
As an algebraic expression it is simply: 18-x
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
It is simply x - 6. The expression cannot be evaluated because the value of x is not given.
You don't "solve" an expression. You can solve an equation; an expression can be simplified or otherwise manipulated, and if you know the value of "x" (in this case), you can evaluate its value.
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.
As an algebraic expression it is simply: 18-x
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
The expression would be written as 16 The value of the expression is 1. 1 x 1 x 1 x 1 x 1 x 1 = 1
579 = 3 x 193
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
Since there is no expression given, there is no sensible answer.
It is an expression whose value will depend on the value of the variable x.
It is simply x - 6. The expression cannot be evaluated because the value of x is not given.
7.7
-3
It is an algebraic expression that can be simplified depending on the plus or minus value of 4
4x^2 + 9 is a prime algebraic expression. Its numerical value may be prime of not - depending on the value of x.For x = 1, the value of the expression is 13 - a prime whereasfor x = 2, the value of the expression is 25 - not a prime.
