It is 2n + 20.
X = " a number " X + 20
Let the number be x and so the expression would be: x+20
4(x + 20)
Hans earned 20 less than ericka algebraic expression
let x = first number let y = second number x + y =20
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
13 + a + 7 = 5 + b - 20. This assumes the two numbers are different.
20 - 4h is an algebraic expression in one variable, h. It cannot be solved since it is not an equation nor an inequality; it cannot be evaluated without any information about h.
It is simply: 5n+20 which is an algebraic expression because it has no equality sign
6*(3+20) = 138
It is simply 2x+20 which is an algebraic expression that has no equality sign.
You have to assign some variable name to "a number", for example, "n". The difference would be: 20 - n Half this difference is: (1/2) (20 - n) Or alternately: (20 - n) / 2
60 - 20 + 70 = 110
(x + y)/20
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
an example of a expression is [7+3] x 20- 7= 13
This is an expression, not an equality (or inequality). It, therefore, cannot have a solution.
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
A factor is a number or algebraic expression by which another is exactly divisible.A multiple is a number or algebraic expression that can be divided by another number or algebraic expression without a remainder.Factors go into numbers, numbers go into multiples.
(x - 5)(x - 2)(x - 2)
