# How do you write a compound inequality from a word problem?

## How do you write a compound inequality from a word problem?

**Let’s say b is the number of books Alex sells per day.****Since we want the profit to be at least $120.00, we want it to be greater than or equal to than $120. We can rewrite this as an inequality.**

## What is an example of an inequality word problem?

For example, **x x26gt; 6 or x x26lt; 2. The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. You can show this graphically by putting the graphs of each inequality together on the same number line.**

## What is an example of a compound inequality?

To solve a compound inequality, **first separate it into two inequalities.****Determine whether the answer should be a union of sets (x26quot;orx26quot;) or an intersection of sets (x26quot;andx26quot;).****Then, solve both inequalities and graph**

## How do you find the inequality of a word problem?

For example, **x x26gt; 6 or x x26lt; 2. The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. You can show this graphically by putting the graphs of each inequality together on the same number line.**

## What is an example of an inequality problem?

Example: **xu221232 x26lt; u22125** Because we are multiplying by a positive number, the inequalities will not change.

## What are inequality word problems?

**Inequality Key Words**

- at least – means greater than or equal to.
- no more than – means less than or equal to.
- more than – means greater than.
- less than – means less than.

## How do you write a compound inequality?

A compound inequality is made up of two inequalities connected by the word u201candu201d or the word u201cor.u201d To solve a compound inequality means **to find all values of the variable that make the compound inequality a true statement. We solve compound inequalities using the same techniques we used to solve linear inequalities.**

## What is a compound inequality and how is it solved?

A compound inequality is **an inequality that combines two simple inequalities.**

## What is compound inequality in math?

There are two types of compound inequalities. They are **conjunction problems and disjunction problems. These compound inequalities will sometimes appear as two simple inequalities separated by using the word AND or OR. When solving u201cand/oru201d compound inequalities, begin by solving each inequality individually.**

## How do you find inequalities in word problems?

To solve an inequality, **isolate the variable on one side with all other constants on the other side. To accomplish this, perform opposite operations to manipulate the inequality. First, isolate the x by multiplying each side by two. Whatever you do to one side you must also do to the other side.**

## How do you find the inequality?

Example: **xu221232 x26lt; u22125** Because we are multiplying by a positive number, the inequalities will not change.

## What is an inequality problem?

The word inequality means **a mathematical expression in which the sides are not equal to each other. Basically, an inequality compares any two values and shows that one value is less than, greater than, or equal to the value on the other side of the equation.**

## What are some real life examples of inequalities?

**Roads have speed limits, certain movies have age restrictions, and the time it takes you to walk to the park are all examples of inequalities. Inequalities do not represent an exact amount, but instead represent a limit of what is allowed or what is possible. Equations represent values that are equal.**

## What are examples of inequalities?

The expression **5x u2212 4 x26gt; 2x + 3 looks like an equation but with the equals sign replaced by an arrowhead. It is an example of an inequality. This denotes that the part on the left, 5x u2212 4, is greater than the part on the right, 2x + 3. We will be interested in finding the values of x for which the inequality is true.**

## What is an inequality word problem?

Example: **xu221232 x26lt; u22125** Because we are multiplying by a positive number, the inequalities will not change.

## What’s compound inequality?

For example, **x x26gt; 6 or x x26lt; 2. The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. You can show this graphically by putting the graphs of each inequality together on the same number line.**

## How do you write compound inequalities on a number line?

A compound inequality is **an inequality that combines two simple inequalities.**

## What is a compound inequality example?

Compound inequalities are the derived form of inequalities, which are very useful in mathematics whenever dealing with a range of possible values. For example, after solving a particular linear inequality, you get two solutions, **x x26gt; 3 and x x26lt; 12. You can read it as u201c3 is less than x, which is less than 12.**

## What is a compound and inequality?

A compound inequality (or combined inequality ) is **two or more inequalities joined together with or or and . To be a solution of an or inequality, a value has to make only one part of the inequality true. To be a solution of an and inequality, it must make both parts true. For example: xu2264u22123 or xx26gt;2.**
