can you check these? thank you

I don't understand your first two problems.
The next is right.
(s/4) 8 = 5
The last is also right. 
1)write a 2 step equation:
1) half a dollar minus five dollars equals fifteen dollars:
n/2 5 = 15
no im not sure on this one
2) five hours more than one half of an hour equals fifteen hours:
n/2 + 5 = 15
so n = 20
20/2 is 10 + 5 = 15 
Translate threefourths less than a number
