Lets say
Jill=J
Meg=m
Beth=b
Jill is 4 years younger than meg so j+4=m
This is because if you add 4 to Jill's age, her age is going to be Megs age
Hope this helps and a brainliest would be appreciated
On the right side, there are
• 2•2 = 4 atoms of Nb
• 2•5 = 10 atoms of O

4 Nb + 5 O₂ → 2 Nb₂O₅
Answer:
4
Step-by-step explanation:
I think s(2s) = 205
