2x+3
As an algebraic expression this is written 2x - 12, where x is the unknown number.
If the unknown number is q then: 2q+25 = 72
It is an algebraic expression in the form of 2x+6 whereas x is the unknown variable
Let the unknown number be x: x-4 = 2x -4 = 2x-x -4 = x So the number is -4
twice an unknown number less one and one-half times the same number equals two ---- Let the unknown number be "x":: Equation: 2x - (3/2)x = 2
You have to know the value of the unknown number to give the correct answer.
2x+3 where x is the unknown number
Let the unknown number be x and so the expression is: 2x-3
2x+3
As an algebraic expression this is written 2x - 12, where x is the unknown number.
Let the unknown number be x and so the algebraic expression is: 2x -13
the unknown number is 30 as 50 = x +2(10) so 50 = x+20 so 30 = x
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.
If the unknown number is q then: 2q+25 = 72
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.
The algebraic expression for "twice a number" would be 2x, where x represents the unknown number. To find the quotient of 2x and 6, you would divide 2x by 6, which simplifies to (2x) / 6. This can be further simplified to x / 3, which represents the final quotient of twice a number and 6 in algebraic expression.
