Which procedure can be used to solve the equation 540 = 12 z, and what is the solution? Multiply both sides by 12; the solution is 6,480. Multiply 12 z by 12; the solution is 540. Divide both sides by 12; the solution is 45. Divide 12 z by 12; the solution is 540.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
