One Step Inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does it mean to 'flip' the inequality symbol?

Back

Flipping the inequality symbol occurs when multiplying or dividing both sides of an inequality by a negative number.

Front

Solve the inequality: x - 2 > -18

Back

x > -16

Front

Solve the inequality: 2x > -18

Back

x > -9

Front

What is the solution to the inequality: -2x > -18?

Back

x < 9 (the symbol flips because we divided by a negative number).

Front

Match the inequality with its graph: 11 ≤ a

Back

The graph shows a closed circle at 11 and shading to the right.

Front

Solve the inequality: -4 + y < -8

Back

y < -4

Front

Solve the inequality: 1.8m ≥ -5.4

Back

m ≥ -3

Front

Solve the inequality: (n/3) > -20

Back

n > -60

Front

What does the symbol '≥' mean?

Back

It means 'greater than or equal to'.
