<h3>Operations on Algebraic Expressions: </h3>
- The three major components of an algebraic expression are variables, constants, and coefficients. Addition, subtraction, multiplication, and division are the four fundamental operations. We solve both difficult and straightforward equations using operations on algebraic expressions.
- There are three categories of algebraic expressions: monomial, binomial, and polynomial or multi-term expressions.
- These are the algebraic terms:
- Alphabetic letters alone or in combination with numbers or fractions are the variables.The numbers that are connected to the variables in a single term are called coefficients.
- Constants: Single integers or numbers that are typically connected to other terms through elementary operations.Examples include 8xyz, 25x+12y+9, 2yz23zy, and 3a+2b+5c.
Algebraic Expression Types
There are three different categories for algebraic expressions. As follows:
- Expressions with a monomial or single word. For instance, 4xy2, 3ab, 7p, 5xyz, etc., where 3,4,5,7 are the coefficients and x, y, z, a, b, p are the variables.
- Expressions with two terms or a binomial. For instance, 2xyx, pq5p2, etc.
- Multi-term or polynomial expressions. as in 2x+5y4, 2xy2+3y+1, etc.

Answer:
First is 144
Second is 16
Third is 9
Step-by-step explanation:
To find the distance between two numbers on the number line, you have to subtract the smallest one to the greatest one. In this case, the distance from 7 to 10 is 10 - 7 = 3
Using a system of equations, it is found that she has 9 picture books.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Number of picture books.
- Variable y: Number of encyclopedias.
- Variable z: Number of fairy tale books.
The ratio of the number of picture books encyclopedias, and fairy tale books Annette had is 3:4:5, hence:
She gave half of her encyclopedias to her brother and he gave her 5 books of fairytales. Now she has 14 more books of fairy tales than encyclopedias, hence:
z + 5 - 0.5y = 14.
z - 0.5y = 9
From the ratios, we have that:
Hence we solve for x to find the number of picture books:
x = 9.
