About 20/20 Linear Inequalities
A power learning aid combines Coaching Calculators, Practice and Guide to help students master linear inequalities.
The Coaching Calculators focus on one-step, two-step and multi-step linear inequalities as well as those containing parentheses, decimals and fractions :
one-step : x − 2 ≤ 3 , x/7 ≥ 2
two-step : 3x + 8 ≤ 20, 2 ≥ 5 − 6x
multi-step : 4 + 9x ≥ 2x − 18
parentheses : 2(3 − 4x) ≤ 2x + 9
decimals : 0.25x + 1.5 = 9.9 − 0.2x
fractions : (1/2)x − 5 ≥ 3x + 1/5
Practice focuses on all of the above as well as harder inequalities with parentheses and fractions :
10 − 3(2 − 3(x + 5)) = 2x + 9
(1/2)(2x − 5) ≥ 3x + 3/4
Students learn quickly as they work with Coaching Calculators and Practice to review each step of the solving process.
The Guide includes step-by-step worked examples that highlight key differences between solving linear inequalities and solving linear equations.
