Thrice A number divided by five is three
2x-3
As an algebraic expression this is written 2x - 12, where x is the unknown number.
The algebraic expression for three less than an unknown number, typically represented as ( x ), is ( x - 3 ). This expression indicates that you subtract 3 from the unknown number ( x ).
x/2 - 3/4
The number could be -12.5326 or 10.5326 (approx).
3a-6x2
As an algebraic expression it is: 2x-9
2x-3
As an algebraic expression this is written 2x - 12, where x is the unknown number.
x / (2y - 7)
2x-3 , where x is the number referred to in the question
Let the unknown number be x and so the algebraic expression is: 2x -13
The corresponding expression would be 2x - 6 = 4.
3n-9
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
