Part V: Practice-Review-Analyze-Practice
49. B. Combine all x’s and then all y’s:
6x+ x= 7x(remember x = 1x)
2y+ y= 3y(and y= 1y)
The answer is:
7x+
3y
Note: You can’t combine 7x and 3y because the letters are different. You can only combine
like terms.
50. B. Using 150 of each kind of ticket assumes that an equal number of each kind were sold:
150 + 150 + 150 = 450. But since you know that three times as many senior citizens’ tickets
were sold as adults’ tickets, if 150 adults’ tickets were sold, that would mean 450 senior
citizens’ tickets were sold, for a total of 600 for the adults and senior citizens.
Therefore, you know — since the total of all the tickets is 450 — that the adults’ tickets
sold must be fewer than 150.
