The answer is D, because you move to the right of the decimal to see if that number is 5 or above. Then you round up, (toΒ 86). :) Hope this was helpful.
Follow these steps using the algebra tiles to solve the equation β5x + (β2) = β2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
