Answer: D. 154.8 ≥ x ≤ 155.6
Step-by-step explanation:
We are told that it varies the most by 0.4, so this means that it cannot be a value less than 154.8 or exceed a value greater than 155.6.
Since it says by most, we know it is an inequality that is greater than/less than or equal to. x is the weight of the object.
Subtract 0.4 from 155.2 and you get 154.8, which is the minimum value. You obtain the inequality 154.8 ≥ x.
Add 0.4 to 155.2 and you get 155.6, which is the maximum value. You obtain the inequality x ≤ 155.6.
We can take these two inequalities to create a compound inequality that represents the weight of the object.
Our final answer would be D. 154.8 ≥ x ≤ 155.6
