What are equivalent expressions in algebra?
An equivalent expression is an expression that has the same value or worth as another expression, but does not look the same. An algebraic example of equivalent expressions is: 2(2x – 3y + 6) is equivalent to 4x -6y + 12.
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.
What is the equivalent of 42 35?
Answer: Yes, these are equivalent because 42+35=77 and 7(6+5)=77.
What is the easiest way to 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.
How do you write an expression equivalent to 7 8?
So, 7/8 = 35/40.
What is the meaning of equivalent expression?
What are equivalent expressions? 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 is the lowest term of 15 12?
4/5
In our example of 12/15 = (2 x 2 x 3) / (3 x 5), we can divide the top and bottom by the common factor 3. When we do so, we find that 12/15 = (2 x 2) / 5 or 4/5. So the fraction 12/15 can be simplified or reduced to become the fraction 4/5.
How do you write an equivalent variable expression?
You can write equivalent expressions by combining like terms. Like terms are terms that have the same variables raised to the same powers. For example, the list shows some pairs of like terms. the new coefficient is 9.
