TEST Like terms,3os, f to d

Front

What are like terms in algebra?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 4y are not.

Front

How do you simplify the expression 90 - 5^2 x 3?

Back

First, calculate 5^2 = 25. Then multiply by 3: 25 x 3 = 75. Finally, subtract from 90: 90 - 75 = 15.

Front

What is the result of combining the like terms in the expression 6x + 1 - 7x?

Back

Combine like terms: 6x - 7x = -x. The expression simplifies to -x + 1.

Front

What does the expression v + v + v + v + v simplify to?

Back

It simplifies to 5v, as you are adding the same term (v) five times.

Front

How do you convert the fraction \( \frac{-2}{3} \) to a decimal?

Back

Divide -2 by 3 to get -0.666..., which can be expressed as -0.\overline{6}.

Front

What is 2 4/5 as a decimal?

Back

Convert 4/5 to decimal (0.8) and add to 2: 2 + 0.8 = 2.8.

Front

What is the definition of a variable in algebra?

Back

A variable is a symbol (often a letter) that represents a number in mathematical expressions or equations.

Front

What is the distributive property in algebra?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a parenthesis.

Front

How do you evaluate the expression 3(x + 4) when x = 2?

Back

Substitute x with 2: 3(2 + 4) = 3(6) = 18.

Front

What is the process of combining like terms?

Back

Combining like terms involves adding or subtracting coefficients of terms that have the same variable and exponent.
