How do you create an algebraic expression?

The expression 9 + x represents a value that can change. If x is 2, then the expression 9 + x has a value of 11. If x is 6, then the expression has a value of 15. So 9 + x is an algebraic expression.

What are the examples of expression?

The definition of an example of expression is a frequently used word or phrase or it is a way to convey your thoughts, feelings or emotions. An example of an expression is the phrase “a penny saved is a penny earned.” An example of an expression is a smile.

How do you do simple expressions?

Here are the basic steps to follow to simplify an algebraic expression: remove parentheses by multiplying factors. use exponent rules to remove parentheses in terms with exponents. combine like terms by adding coefficients.

How do you find expressions?

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

What expression is equivalent to 100000?

Meanwhile, the exponent of the “exponential term” of 100,000 is 5 because the decimal point in the “digit term”, 1, must be moved five times to the right to arrive at 100,000. The exponent is positive because 100,000 is greater than or equal to ten. Therefore, the expression that is equivalent to 100,000 is C. .

How do you identify an algebraic expression?

Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation. For example, 2x+4y−9 is an algebraic expression. Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.

What is an example of an equivalent expression?

Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them. Example 1: Are the two expressions 2y+5y−5+8 and 7y+3 equivalent? Explain your answer.

What is equivalent expression?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

What expression is equivalent to 16?

Answer: Expression 6 is equal to 16.

How do you solve algebraic expressions with variables?

Here’s how you would do it:
1. (x + 3)/6 = 2/3. First, cross multiply to get rid of the fraction.
2. (x + 3) x 3 = 2 x 6 =
3. 3x + 9 = 12. Now, combine like terms.
4. 3x + 9 – 9 = 12 – 9 =
5. 3x = 3. Isolate the variable, x, by dividing both sides by 3 and you’ve got your answer.
6. 3x/3 = 3/3 =
7. x =1.

How do you expand and simplify algebraic expressions?

Expanding brackets
1. To expand a bracket means to multiply each term in the bracket by the expression outside the bracket. For example, in the expression 3 ( m + 7 ) , multiply both. and 7 by 3, so:
2. Expanding brackets involves using the skills of simplifying algebra. Remember that 2 × a = 2 a and a × a = a 2 .
3. Expand 4 ( 3 n + y ) .
