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.
Double mean to multiply.For example: the algebra expression 2x can be written in the English Phrases like-Double a Number-Twice a number-Two of a number-Two times a number-or the product of two and a number.

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.

twice the difference of three times a number and eight
The difference between five times a number and twice that number can be expressed mathematically. If we let the number be represented by ( x ), then five times the number is ( 5x ) and twice that number is ( 2x ). The difference is calculated as ( 5x - 2x ), which simplifies to ( 3x ). Thus, the difference is three times the original number.
Twice the difference of a number and ten can be expressed as ( 2(x - 10) ), where ( x ) represents the number. This means you first find the difference between the number and ten, and then multiply that result by two. For example, if the number is 15, the expression would evaluate to ( 2(15 - 10) = 2 \times 5 = 10 ).
2(x - 7) = 8
Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.

Let the number be x and so the expression is 4x -3
It is 3*n - 5
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 you have a number x, then twice that number is 2*x and so the expression means 42 - 2*x
2 x = 8 + 4x
