Solve two-step linear equations containing integers and rational coefficients (e.g., 3x - 7 = 14).
Solve two-step linear equations containing integers and rational coefficients (e.g., 3x - 7 = 14).
Master addition, subtraction, multiplication, and division rules with signed negative numbers.
Identify proportional relationships. Use tables, graphs, and equations to explain a constant rate.
Show each step. Tax and tips are calculated on the stated base. Round final money amounts to the nearest cent.
Calculate with signed fractions and decimals. Explain sign rules or model a sum on a number line.
Solve each inequality and graph the solution on a number line. Use an open circle for < or > and a closed circle for β€ or β₯.
Use the stated scale. Distinguish a length scale factor from an area scale factor.
List equally likely outcomes before calculating probabilities. Experimental results may differ from theoretical probabilities.
