2x-3=x+2
answer x=5
2x+3
Let the number be x and so the expression is: 2x+3
This is an algebraic expression. It can be written as 3(2x + 4)
2n
If the number is represented by variable x, then twice the number is represented by 2x.
2(ab)
2x+3
Let the number be x and so the expression is: 2x+3
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
This is an algebraic expression. It can be written as 3(2x + 4)
Let the unknown number be x and so the expression is: 2x-3
2n
Twice a number can be represented as 2x, where x is the unknown number. Adding 27 to this expression gives 2x + 27. Therefore, "twice a number plus 27" can be written as the algebraic expression 2x + 27.
If the number is represented by variable x, then twice the number is represented by 2x.
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.
