Chapter 1: Q62. (page 31)

Write a variable expression to represent the phrase.

The sum of a number and 14.5

Short Answer

Expert verified

The variable expression will be: x + 14.5; where x is the number.

Step by step solution

01

Step 1: Definition of an Algebraic Expression

An algebraic expression (or) avariable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc

02

Example of Algebraic Expression

A variable is a letter whose value is unknown to us.

For example, y is our variable in the expression, 10y + 63. A constant is a term that has a definite value. Here 10y is the variable term and 63 is a constant term.

03

Step 3: The sum of a number and 14.5 

The phrase sum means addition and difference means subtraction.

Assume the unknown number to be x and x can be any integer, then the sum of a number and 14.5 will be x + 14.5.
