Question

5 subtracted from the quotient of z and 5 is equal to 10​

Answer 1

Answer:

In other words, the three main components of algebraic expressions are numbers, variables, and arithmetic operations.

NUMBERS OR CONSTANTS

Examples: 11, 66, 88, 2727, 3232, etc.

VARIABLES OR LETTERS

Examples: xx, yy, aa, hh, pp, etc.

ARITHMETIC OPERATIONS

Examples: ++ (addition), -− (subtraction) , \times× (multiplication) , ÷÷ (division)

The following are easy examples that can help you get familiarized with the operations of addition, subtraction, multiplication, and division.

Addition

the sum of xx and 55 → x+5x+5

Subtraction

the difference of yy and 33 → y-3y−3

Multiplication

the product of nn and 22 → 2n2n

Division

the quotient of kk and 77 → \Large{{k \over 7}}

Writing Algebraic Expressions Step-by-Step Examples

Let’s go over more examples.

Example 1: The sum of twice a number and 33

Answer: Let variable xx be the unknown number. So twice a number means 2x2x. The sum (use plus symbol) of twice a number and 33 can be written as 2x+32x+3.
