GED Math Extra Prep: Inequalities
Inequality problems on the GED Math test often involve isolating a variable, but they may also simply ask you to convert a statement into its equivalent mathematical form. The following practice questions ask you to do both.
- What is the correct way of writing “x is less than 5 but greater than or equal to –3″?
- Anne plans to spend no more than $60 ordering socks for school. The online sock company charges a shipping fee of $15 for any order. The inequality
represents the number of pairs of socks Anne can order from the company. What is the maximum number of pairs of socks that Anne can buy?
Answers and Explanations
- The correct answer is C.
Deal with each part of the statement separately: “x is less than 5″ can be written as x < 5, and “x is greater than or equal to –3″ can be written as
Now combine both statements by placing x in the middle:
Hence, Choice (C) is correct.
- The correct answer is 9.
represents the number of pairs of socks Anne can order from the company. Subtracting 15 from each side of the inequality gives you
This can be reduced further by dividing both sides by 5, giving you
