Shown,
2/5x+3/10x= 4/10x+3/10x=7/10x
That's correct.

(2/5x) + (3/10x) =
Multiply the first term by 2/2 to convert to the least common denominator of 10x:
(2*2/2*5x) + (3/10x) =
(4/10x) + (3/10x) =
Then just add:
(4+3)/10x =
7/10x

Yes, that's right. To make a common denominator of 10x we multiply the first fraction by 2/2 to get 4/10x + 3/10x; since they now have the same denominator we add the numerators to get 7/10x.

2/5x + 3/10x = 4/10x + 3/10x = 7/10x
Yes it is so no explanation is necessary.
