What is an example of inequality?
The definition of inequality is a difference in size, amount, quality, social position or other factor. An example of inequality is when you have ten of something and someone else has none. The inequality x is less than y, together with that y
What is inequality in real life?
Think about the following situations: speed limits on the highway, minimum payments on credit card bills, number of text messages you can send each month from your cell phone, and the amount of time it will take to get from home to school. All of these can be represented as mathematical inequalities.
How do you describe inequality words?
An inequality is a mathematical statement that compares two expressions using the ideas of greater than or less than….Inequality Signs.
| Symbol | Words | Example |
|---|---|---|
| < | less than | 2<11 , 2 is less than 11 |
| ≥ | greater than or equal to | 4≥4 4 ≥ 4 , 4 is greater than or equal to 4 |
Inequality Signs
| Symbol | Words | Example |
|---|---|---|
| > | greater than | 5>1 , 5 is greater than 1 |
| < | less than | 2<11 , 2 is less than 11 |
| ≥ | greater than or equal to | 4≥4 4 ≥ 4 , 4 is greater than or equal to 4 |
| ≤ | less than or equal to | 7≤9 7 ≤ 9 , 7 is less than or equal to 9 |
What does the word inequality?
1 : the quality of being unequal or uneven: such as. a : social disparity. b : disparity of distribution or opportunity. c : lack of evenness. d : the condition of being variable : changeableness.
Why inequality is a problem?
Enough economic inequality can transform a democracy into a plutocracy, a society ruled by the rich. Large inequalities of inherited wealth can be particularly damaging, creating, in effect, an economic caste system that inhibits social mobility and undercuts equality of opportunity.
How to write an inequality for a real world situation?
Step 1: Given eraser cost = $1; pencil cost = $0.25. Amount paid = 0.25p + 1 ≤ 9. Step 2: Inequality representing the above real-world situation is 0.25p + 1 ≤ 9. Example 2. More than 370 students went on a field trip. Twelve buses were filled and 10 more students traveled in a car.
How are equations used to solve word problems?
To solve word problems we need to write a set of equations that represent the problem mathematically. The solution of the equations is then the solution to the problem. Read the whole question.
How are problems set up in a system of equations?
Typically, the problems are set up such that there is only one variable on each side of the equation and at least one variable has a leading coefficient equal to one. The other equation has two variables, as well, each on the same side of the equation.
How to solve an equation for an unknown quantity?
Assign a variable to the unknown quantity, for example, \\ (x\\). Translate the words into algebraic expressions by rewriting the given information in terms of the variable. Set up an equation or system of equations to solve for the variable. Solve the equation algebraically using substitution. Check the solution.
