1. n - 25.4 = 44.8 Add 25.4 on the variable side to cancel the number out, then do the same on the right. 44.8 -25.4

19.4 N = 19.4

2. Y = -14 Find as many equations as possible with this answer.

2A. Y + 13 = -1 Subtract 13 from -1 and 13 (which cancels).

Interpreting Graphs
Which graph am I referring to, Map G or Map M? I walk to Publix to get deli food, which has a line. After standing in line waiting my turn, I purchase my order and head to the checkout. There is another line I must wait for. After purchasing there I leave Publix and head home. Which graph matches the data? Answer: Graph G it was easy. The line first goes up when I walk to Publix, and the first flat line is when I wait in line to get deli food. The line goes up again to go to the checkout, where it flattens again when I wait in line at the checkouts. The line finally goes down when I leave Publix and walk home. A situation matching the Graph M Interpretation would be a Publix employee at 5:00 PM (rush hour) who is very alert. The employee then falls asleep at 12:00 AM (midnight) when Publix closes and fails to get out. He winds up staying asleep until he half-wakes up at 6:00 AM when Publix opens up again. The exhausted employee gets less and less tired until he drinks a cup of decaf coffee giving his full awakeness back an hour later in time for his first customer.
