Final answer:
To apply the addition property of inequality to the inequality 2x + 100 < 130, subtract 100 from both sides, then divide by 2 to solve for x. The solution is x < 15.
Step-by-step explanation:
To apply the addition property of inequality to the inequality 2x + 100 < 130, you need to isolate the variable x. Start by subtracting 100 from both sides of the inequality:
2x + 100 - 100 < 130 - 100
2x < 30
Next, divide both sides of the inequality by 2 to solve for x:
2x/2 < 30/2
x < 15
So, the solution to the inequality is x < 15.
