Mike had 5 blue squares, 4 blue rectangles and 3 small squares. molly added 3 blue squares, 7 blue rectangles and 4 small squares. write an equation that shows mike's tiles, molly added tiles and the total combined tiles.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
