What this topic is

Inequalities on the SHSAT Mathematics section cover writing and solving comparison statements that use less than, greater than, or the inclusive versions of those relations.

A student must translate a word problem, such as a budget for buying items, into an inequality, solve a linear inequality, and count the integers or positive integers that satisfy it. The exam typically asks which inequality represents a situation or how many integer values work.

Traps include reversing the inequality when multiplying by a negative, mixing open and closed signs, and counting the wrong set of integers. Choices usually show rival inequalities or possible counts.

Sample questions

Pick an answer to see whether it is right — nothing is saved, and nothing needs an account.

Question 1Mid

How many integers xx satisfy 2<x534-2<\dfrac{x-5}{3}\le4?

Show answer

Answer: C — 18

Multiplying by 3 gives 6<x512-6<x-5\le12. Adding 5 gives 1<x17-1<x\le17, so xx can be any integer from 0 through 17. There are 18 integers.

Question 2Easier

Maya has $15 to spend on notebooks that cost $3 each. Which inequality represents nn, the number of notebooks she can buy?

Show answer

Answer: A — 3n153n \le 15

Each notebook costs $3, so nn notebooks cost 3n3n dollars, which must be at most 15: 3n153n \le 15.

Question 3Mid

How many positive integers xx satisfy 2x3<72x - 3 < 7?

Show answer

Answer: B — 4

2x3<72x - 3 < 7 gives 2x<102x < 10, so x<5x < 5. The positive integers less than 5 are 1,2,3,41, 2, 3, 4, which is 4 values.
