F = 4J
F+J>= 55
4J + J >= 55
5J >= 55
J = 11
Enter an inequality that can be used to represent this situation in the first box, where x represents Julio's age.
Enter the youngest age Julio can be in the second box.
F+J>= 55
4J + J >= 55
5J >= 55
J = 11
Let x represent Julio's age.
Julio's father is 4 times as old as Julio: 4x is the father's age.
The sum of their ages is no less than 55: x + 4x ≥ 55.
Simplifying the inequality:
x + 4x ≥ 55
5x ≥ 55
To find the youngest age Julio can be, we need to solve this inequality for x. Dividing both sides by 5:
5x/5 ≥ 55/5
x ≥ 11
Therefore, the inequality that represents the situation is 5x ≥ 55, and the youngest age Julio can be is 11 years old.
