An object has a mass of 400 g and a volume of 25 cm3.
Find the density of the object in g/cm3.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Me d is also an option but i couldn't get it in the picture

Which ordered pair is a solution of the equation? 2x+3y=10
