Gretchen is setting up for a banquet. she has 300 chairs and needs to distribute them evenly among t tables. how many chairs should she put at each table? write your answer as an expression.

14+2 (56-1) this is an arithmetic sequence

Suppose you are analyzing the relationship between time and distance given in a table, and there are 4 values for each quantity. you divide distance 2 minus distance 1 by time 2 minus time 1.you then divide distance 4 minus distance 3 by time 4 minus time 3 and get a different answer. what can you say about the relationship?
