Equations and inequalities (Math 1)

Practice 5 items →

Identity, contradiction, or one number. Students solve with variables on both sides, recognize 0 = 0 and 0 = k, rearrange literal equations, and solve compound AND/OR inequalities.

Part no. is the node's id; the realm is the kind of math; qty is how many practice items it carries.

Students can

variables on both sides; $0=0$ vs $0=k$ ; literal equations ( $d=rt\Rightarrow t=d/r$ ); compound inequalities AND / OR.

Ready when

they classify $2(x-3)=2x-6$ as identity and solve $\frac{x+1}{2}\ge 4$ on a line.

Formulas

Literal equation

d = rt \implies t = \frac{d}{r}

Watch for

dividing by a coefficient that might be zero; AND graphed as two rays.
