What is 5x 10 factored?
we see that 5 is a common factor of 5x and 10, because 5 can divide 5x and 10. so if we take out a 5 from 5x+10, we get 5(x+2).
What is the GCF of 5x 10?
We found the factors and prime factorization of 5 and 10. The biggest common factor number is the GCF number. So the greatest common factor 5 and 10 is 5.
What is the constant in this expression 5x 10?

What is constant example?
A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in “x + 5 = 9”, 5 and 9 are constants.
What is 5x in algebra?
If you mean that the variable x takes on a value of 6.15, then simply replace x by 6.15 in the expression 5x and evaluate that. And, again, 5x means 5 times x.
Is 5 an algebraic expression?
The expressions in which the numbers, or variables, or both, are connected by operational signs (+, – etc.) are called algebraic expressions. For example 5, 4x, a+b, x−y etc.
Why do we use algebra?
Algebra is an important life skill worth understanding well. It moves us beyond basic math and prepares us for statistics and calculus. Algebra is useful around the house and in analyzing information in the news. It also reinforces logical thinking and is beautiful.
What are the 4 steps to solving an equation?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division.
What is the golden rule for solving equations?
Do unto one side of the equation, what you do to the other! An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
How do you simplify equations?
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.
- combine the constants.
What is an example of simplify?
Example 1: Simplify: 5(7y+2) 5 ( 7 y + 2 ) . Solution: Multiply 5 times each term inside the parentheses. Example 2: Simplify: −3(2×2+5x+1) − 3 ( 2 x 2 + 5 x + 1 ) . Because multiplication is commutative, we can also write the distributive property in the following manner: (b+c)a=ba+ca ( b + c ) a = b a + c a .
