Answer:
4th option because the two negatives will become positive and the 3rd will make it negative again
The area of the top of the table is 28 × 20 = 560 cm2. The area of Patty’s tiles is 8 cm2 each and the area of Jake’s tiles is 9 cm2 each. Patty will need 560 ÷ 8, or 70, tiles. Jake will need 560 ÷ 9, or about 63, tiles. So, Patty will use about 7 more tiles.
Fourth grade average:
87 + 95 + 76 + 148 + 104 = 510 / 5 = 102
Seventh grade average:
183 + 187 + 204 + 215 + 196 = 985 / 5 = 197
Repeating decimal since it has that elipsis (...)
