Answer:
Step-by-step explanation:
Our inequality is |125-u| ≤ 30. Let's separate this into two. Assuming that (125-u) is positive, we have 125-u ≤ 30, and if we assume that it's negative, we'd have -(125-u)≤30, or u-125≤30.
Therefore, we now have two inequalities to solve for:
125-u ≤ 30
u-125≤30
For the first one, we can subtract 125 and add u to both sides, resulting in
0 ≤ u-95, or 95≤u. Therefore, that is our first inequality.
The second one can be figured out by adding 125 to both sides, so u ≤ 155.
Remember that we took these two inequalities from an absolute value -- as a result, they BOTH must be true in order for the original inequality to be true. Therefore,
u ≥ 95
and
u ≤ 155
combine to be
95 ≤ u ≤ 155, or the 4th option

Since
Our inequality is |125-u| ≤ 30.
Here we have to separate this into two.
Presume that (125-u) should be positive, we have 125-u ≤ 30, and if we assume that it's negative, we'd have -(125-u)≤30, or u-125≤30.
Now there are two inequalities to solve for:
125-u ≤ 30
u-125≤30
So,
For the first one, we can subtract 125 and add u to both sides, resulting in 0 ≤ u-95, or 95≤u. Therefore, that is our first inequality.
Now
The second one can be done out by adding 125 to both sides, so u ≤ 155.
So, it be like
u ≥ 95
and
u ≤ 155
So, finally 95 ≤ u ≤ 155
