What is equivalent expressions worksheet 1?

Equivalent Expressions Worksheet 1 – You will analyze word problems and try to find expressions that model that situation. Plus you’ll determine if expressions are equivalent, and write your own expression

Are the expressions 5(4x + 3) and 20x+3 equivalent?

Are the expressions 5(4x + 3) and 20x + 3 equivalent? Why or why not? Sample answer: Xo, they are not equivalent because the 5 would also need to be multiplied by the 3 because of the distributive property. 5(4x + 3) is really equivalent to 20x + 15.

How do I practice simplifying and finding equivalent algebraic expressions?

With these printable worksheets, students will practice simplifying and finding equivalent algebraic expressions. Most of these worksheets align with CCSS.6.EE.3 and/or CCSS.7.EE.A.1. Combine like terms to simplify each expression. This basic level includes only addition (no subtraction).

Do students match equivalent expressions?

Students match equivalent expressions. These cards include some that require students to use the distributive property and some that do not. For each of these task cards, students will answer a question about equivalent expressions. Some require distributive property, some do not.

How do you find equivalent expressions?

Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.


What is an example of an equivalent expression?

Examples of Equivalent Expressions 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6×2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.


What is an equivalent expression in math?

Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them.

And 3x plus 6 is not equal to 2x + 6 thereby eliminating choice C as well.


How do you write an equivalent expression in standard form?

Two algebraic expressions are equivalent if they always lead to the same result when you evaluate them, no matter what values you substitute for the variables. For example, if x = 3, then x + x + 4 = 3 + 3 + 4 = 10 and 2x + 4 = 2(3) + 4 = 10 also.

Which expression is equivalent to sine of 7pi 6 )?

The value of sin 7pi/6 in decimal is -0.5. Sin 7pi/6 can also be expressed using the equivalent of the given angle (7pi/6) in degrees (210°). Since the sine function is a periodic function, we can represent sin 7pi/6 as, sin 7pi/6 = sin(7pi/6 + n × 2pi), n ∈ Z.
