To make the inequality 2x + 5.5 < 20 true, we need to find two values of x that satisfy the inequality.
First, we can start by isolating x on one side of the inequality by subtracting 5.5 from both sides:
2x + 5.5 - 5.5 < 20 - 5.5
2x < 14.5
Next, we can solve for x by dividing both sides by 2:
2x/2 < 14.5/2
x < 7.25
Therefore, any value of x less than 7.25 will make the inequality 2x + 5.5 < 20 true. For example, x = 2 and x = 5 both satisfy the inequality:
2(2) + 5.5 < 20
4 + 5.5 < 20
9.5 < 20
and
2(5) + 5.5 < 20
10 + 5.5 < 20
15.5 < 20
