Q. Select all of the equations below that are equivalent to:−6=mnUse properties of equality.Multi-select Choices:(A)−2=3mn(B)−5=2mn(C)−3=3mn(D)4=−3mn
Analyze Equation: Step 1: Analyze the original equation and the transformation needed to check equivalency.Original equation: −6=mn.We need to determine if dividing or multiplying both sides of the equation by the same number results in the equations given in the choices.
Check Choice (A): Step 2: Check choice (A) –2=3mn.Divide both sides of the original equation by 3:3−6=3mn,−2=3mn.This matches choice (A).
Check Choice (B): Step 3: Check choice (B) –5=2mn.Divide both sides of the original equation by 2:2−6=2mn,−3=2mn.This does not match choice (B), so it's incorrect.
Check Choice (C): Step 4: Check choice C−3=3mn.Divide both sides of the original equation by 3:3−6=3mn,−2=3mn.This does not match choice C, so it's incorrect.
Check Choice (D): Step 5: Check choice (D) 4=−3mn. Divide both sides of the original equation by −3: −3−6=−3mn, 2=−3mn. This does not match choice (D), so it's incorrect.
