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 in each row

  5

Step-by-step explanation:

80 tiles in 8 equal rows means there are 80/8 = 10 tiles in each row. If half the tiles in a row are blue, there are 10/2 = 5 blue tiles in each row.

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
