The graph shows the number of points Derek scored

8. Write a multiplication equation and
a division equation that compare the

Game1
138 ÷ (6 + 3) = t (138 ÷ 6) + 3 = t
138 ÷ (6 + 3) = t cannot be used. The parentheses
around 6 + 3 tell you to add first. But you must add
the 3 item tables after finding the number of tables
needed for seating. t = 26
