Question

If 5 times a number is increased by 4 the number is at least 19. Write an inequality to represent the situation.

Answer 1

To represent the situation, we can write the inequality 5x + 4 ≥ 19, where 'x' represents the number. Solving the inequality, we find that x ≥ 3.

Step-by-step explanation:

To represent the situation where 5 times a number is increased by 4 and the result is at least 19, we can write the inequality:

5x + 4 ≥ 19

Here, 'x' represents the number. To solve the inequality, we can subtract 4 from both sides to isolate the variable:

5x ≥ 15

Then, divide both sides by 5:

x ≥ 3

Therefore, the inequality that represents the situation is x ≥ 3.
