How do you know if two expressions are equivalent?

If all of the terms in the two expressions are identical, then the two expressions are equivalent. Distribute any coefficients on each side of the equation. Combine any like terms on each side of the equation.

What are equivalent fractions?

Equivalent fractions are fractions with different numbers representing the same part of a whole. They have different numerators and denominators, but their fractional values are the same. For example, think about the fraction 1/2.

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 are some equivalent expressions?

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.

What does it mean for expressions to be equivalent?

Generally, if two things are the same, then it is called equivalent. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. But if the values are plugged in the expression, both the expressions give the same result.

What expression is equal to 81?

Some expressions that are equivalent to 81 are 9^2, 3\times3^3, and 8^2+17.

Are the two expressions equivalent?

Two expressions are equivalent if they can be simplified to the same third expression or if one of the expressions can be written like the other. In addition, you can also determine if two expressions are equivalent when values are substituted in for the variable and both arrive at the same answer.

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.

How do you know if equations are equivalent?

To solve this, you need to find “x” for each equation. If “x” is the same for both equations, then they are equivalent. If “x” is different (i.e., the equations have different roots), then the equations are not equivalent.

What is this expression equivalent to A -> B?

Hence, a. (a+b) is equivalent to a2+ab.

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.

How to make a fraction equivalent?

Multiply both the numerator and denominator of a fraction by the same whole number. As long as you multiply both top and bottom of the fraction by the same number, you won’t change the value of the fraction , and you’ll create an equivalent fraction.

What are Equivalent Fractions?

Equivalent fractions are fractions with different numbers representing the same part of a whole. They have different numerators and denominators, but their fractional values are the same.

What is half of a fraction?

For example, think about the fraction 1/2. It means half of something. You can also say that 6/12 is half, and that 50/100 is half. They represent the same part of the whole. These equivalent fractions contain different numbers but they mean the same thing: 1/2 = 6/12 = 50/100
