2x+3
As an algebraic expression this is written 2x - 12, where x is the unknown number.
To express "16 more than twice a number" in mathematical terms, you would write it as 2x + 16, where x represents the unknown number. This expression indicates that you first multiply the number by 2 (twice the number) and then add 16 to the result.
The phrase "the sum of twice a number and 5 is 17" can be translated into an equation. Let the unknown number be represented by ( x ). The equation can be written as ( 2x + 5 = 17 ).
If the unknown number is q then: 2q+25 = 72
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
To express "16 more than twice a number" in mathematical terms, you would write it as 2x + 16, where x represents the unknown number. This expression indicates that you first multiply the number by 2 (twice the number) and then add 16 to the result.
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.
The phrase "the sum of twice a number and 5 is 17" can be translated into an equation. Let the unknown number be represented by ( x ). The equation can be written as ( 2x + 5 = 17 ).
If the unknown number is q then: 2q+25 = 72
