11.You need 2/3 of the class to complete their
Achieve articles. If there are 27 students, how
many have completed their articles?
12.Each ticket cost $12 and you sold $2,820
worth. Write an equation to find the number
of t tickets sold.
13.Find the graph that represents the equation.
y = 2(x – 2)
Hint: One way to do this kind of problem is to do the following:
1. Make a t-table
2. substitute for x any 2 numbers that are not consecutive (next to each other); Example: 0, 2, or -1, 1,
…Whatever you choose you need to be able to graph the ordered pairs.
3. Take the ordered pairs and graph them.
4. Whichever graph they match is the correct answer.
