Question

Can anybody help me as soon as possible. Model with mathematics. The weight of a pen manufactured at the PEN factory is 8g. The actual weight can vary as much as 2g. Write and solve an inequality to represent all acceptable weights for a pen at this factory.

Answer 1

• [6, 10]

Explanation:

Let the weight of a pen be x

Then its weight can be between

• 8 - 2 = 6 g and 8 + 2 = 10 g

This can be shown as

• 8 - 2 ≤ x ≤ 8 + 2
• 6 ≤ x ≤ 10
• x = [6, 10]
