Answer:
<h2><u><em>
x = 85</em></u></h2>
Step-by-step explanation:
20% of a number is 17 . find the number
divide 17 by 20 and you find 1%, multiply by 100 and you get 100%
x = 17 : 20 * 100
x = 0.85 * 100
x = <u><em>85</em></u>
2 + 3w < -1 < 3w + 5 |subtract 3w from all sides
2 < -1 - 3w < 5 |add 1 to all sides
3 < -3w < 6 |change the signs
-3 > 3w > -6 |divide both sides by 3
-1 > w > -2 → -2 < w < -1 → w ∈ (-2, -1)
