I don't know what ur talking about I'm in 6th grade LOL
Amu of unknown element = 40 - (20% * 40)
= 40 - 8
= 38 amu
therefore, the approximate weight of the unknown element is 38 amu.
hope this helps.

14= 3k-4
_ less than _ = -
3* k simplified= 3k
3(x-4) = 15
Distribute the 3:
3x-12 = 15
Add 12 to both sides:
3x = 27
Divide both sides by 3:
X = 9
The answer is D. 9
