The solution set is {x | x > 18}.
Study Guide and Review - Chapter 5
Solve each inequality. Then graph it on a
number line.
12. x + 8 ≤ 3
20. 4p < 32
SOLUTION: SOLUTION: The solution set is {x | x ≤ −5}.
14. −5 < a + 2
The solution set is {p | p < 8}.
22. −2m > 100
SOLUTION: SOLUTION: Since −7 < a is the same as a > −7, the solution set is
{a | a > −7}.
The solution set is {m | m < −50}.
16. y + 1 ≤ 8
SOLUTION: The solution set is {y | y ≤ 7}.
Solve each inequality. Graph the solution on a
number line.
24. MOVIE RENTAL Jack has no more than $24 to
spend on DVDs for a party. Each DVD rents for $4.
Find the maximum number of DVDs Jack can rent
for his party.
SOLUTION: The phrase no more than means the same as less
than or equal to. Let d be the number of DVDs Jack
rents. Write an inequality.
18. SOLUTION: The solution set is {x | x > 18}.
The solution set is {d | d ≤ 6}. So, the maximum
number of DVDs Jack can rent is 6.
29. Four times a number decreased by 6 is less than −2.
Define a variable, write an inequality, and solve for
the number.
SOLUTION: Let x = the number.
20. 4p < 32
