315-1 Solving Inequalities by Addition and Subtraction
The inequality is true when n is greater than or equal to 6, so the solution checks.
Three more than a number is less than twice the number.
Let n = the number.
The solution set is {n | n > 3}.
To check substitute three different values into the original inequality: 3, a number less than 3, and a number greater
than 3.
The inequality is true when n is greater than 3, so the solution checks.
A thrill ride swings passengers back and forth, a little higher each time up to 137 feet. Suppose the
height of the swing after 30 seconds is 45 feet. How much higher will the ride swing?
The ride will swing no higher than 92 more feet.
Solve each inequality. Then graph the solution set on a number line.
