Gia has 80 tiles each tile is white or blue she arranges the tiles in 8 equal rows each row has an equal number of white and blue tiles how many blue tiles are in each row

5 blue and 5 white tiles per row

Step-by-step explanation:

80/8 =(10-this is the amount per row)then divide 10 by 2 to factor in your different different tiles)

Work Check:

80/8rows=10/2colors=5 this means 5 blue and 5 white per row

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
