Concept explainers

Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition

Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

Question

Chapter 0.6, Problem 13E

To determine

To solve the equation m−21<8

Expert Solution & Answer

Answer to Problem 13E

m<29

Explanation of Solution

Given Information: m−21<8

Formula Used : Linear inequality with one variable

Calculation:

Given equation is

m−21<8

To isolate the variable m, adding 21 both sides-

m−21+21<8+21

This gives

m<8+21

Hence the final answer is,

m<29
