Answer:
- |w -30| > 1.6
- (-∞, 28.4) U (31.6, ∞)
Step-by-step explanation:
1. The snack bags will be rejected if their weight differs from 30 grams by more than 1.6 grams:
|w -30| > 1.6
__
2. This inequality resolves to two inequalities.
w -30 > 1.6
w > 31.6 . . . . . add 30
and
-(w -30) > 1.6
w -30 < -1.6 . . . multiply by -1
w < 28.4 . . . . . add 30
The solution in interval notation is the union of the two disjoint intervals:
(-∞, 28.4) U (31.6, ∞)

Answer:
x=6
Step-by-step explanation:
1) Expand the equation to -2x+12=2x-12
2) Subtract 12 from both sides which gives you -2x=2x-24
3) Simplify, which makes it -4x=-24
4) Divide by 4, which gives you 6.
