What has a sum of 16 and a difference of 4?

What has a sum of 16 and a difference of 4?

Answer: 10 and 6. 10-6=4.

When 4 times a number is added to the square?

Answer. Let the required number be x. Then, four times the number is 4x. Hence, the required number is 8.

What is the sum of 15 and the product of 5 and V?

1 Answer. 15+5v means “the sum of 15 and the product of 5 and v”.

How do you write an algebraic expression?

This is the correct way to write the expression. Based on the order of operations, always solve operations in parentheses first. Here, you’d add 4 + 2, then multiply that sum by 5—in other words, exactly what was written in the original expression.

What are the examples of expression?

The definition of an example of expression is a frequently used word or phrase or it is a way to convey your thoughts, feelings or emotions. An example of an expression is the phrase “a penny saved is a penny earned.” An example of an expression is a smile.

How do u write an expression?

To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.

How do you find expressions?

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

Can you solve an expression?

An algebraic expression is a mathematical phrase that can contain numbers and/or variables. It does not contain an equals sign and cannot be solved. An algebraic equation, however, can be solved, and does include a series of algebraic expressions separated by an equals sign.

How do you identify an algebraic expression?

Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation. For example, 2x+4y−9 is an algebraic expression. Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.

What is it called to find the value of an algebraic expression?

Answer Expert Verified. It is called evaluating expression. In order to find the value of an algebraic expression you need to substitute a number for each variable and perform the arithmetic operations and the letters can stand for the numbers and it is called evaluating the expression.

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.

What is value of expression?

The value of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are assigned values. The value of a function, given the value(s) assigned to its argument(s), is the quantity assumed by the function for these argument values.

Which of the following is an example of an algebraic expression?

Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

What are the steps in simplifying algebraic expression?

To simplify any algebraic expression, the following are the basic rules and steps:

1. Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2. Use the exponent rule to remove grouping if the terms are containing exponents.
3. Combine the like terms by addition or subtraction.
4. Combine the constants.

What are the types of algebraic expression?

There are 3 main types of algebraic expressions which include:

• Monomial Expression.
• Binomial Expression.
• Polynomial Expression.

What is terms in algebraic expression?

Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or J sign. In , the terms are: 5x, 3y, and 8. If the variable does not have an exponent, the degree is 1.

What does terms mean in algebra?

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

What is degree in algebraic expression?

Polynomials in two variables are algebraic expressions consisting of terms in the form axnym a x n y m . The degree of each term in a polynomial in two variables is the sum of the exponents in each term and the degree of the polynomial is the largest such sum.

What is the degree of √ 5?

1/2

What is a degree in math called?

A Bachelor of Mathematics is an undergraduate academic degree awarded for successfully completing a program of study in mathematics or related disciplines, such as applied mathematics, actuarial science, computer science or statistics. The Bachelor of Mathematics degree is frequently abbreviated as B. Math or BMath.

What is constant in algebraic expression?

Constants. Constants are the terms in the algebraic expression that contain only numbers. That is, they’re the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.

What is constant and example?

more 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 constant and variable in algebra?

Algebra – Basic Definitions A Variable is a symbol for a number we don’t know yet. It is usually a letter like x or y. A number on its own is called a Constant.

What is like terms in algebraic expression?

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

How do you find the like terms of an algebraic expression?

When we look at algebraic terms to find like terms, first we ignore the coefficients and only look if terms have the same variables with same exponents. Those terms which qualify this condition are called like terms. All the given four terms are like terms, because each of them have the same single variable ‘a’.

What are variables in maths?

Variable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. Commonly used variables include x and y (real-number unknowns), z (complex-number unknowns), t (time), r (radius), and s (arc length).
