Question

1) Twice the difference of Felipe’s age, f and 4 is at least 2. What are the possible values for Felipe’s age?

Answer 1

f ≥ 5

Explanation:

Translating the word problem into an algebraic expression, we have;

2(f - 4) ≥ 2

Opening the bracket, we have;

2f - 8 ≥ 2

Rearranging the equation, we have;

2f ≥ 2 + 8

2f ≥ 10

Dividing both sides by 2, we have;

f ≥ 5

Therefore, the possible values for Felipe’s age is 5, 6, 7, 8, 10 till infinity.
