30 of them with a remainder of 15
7 hours subtracted by 30 minutes = -23
1980 subtracted by 2010 = -30
You said that " 7x - 4x = 30 ".From only that much information, I can see that 3x must be 30,which leads me directly to the realization that 'x' is 10 .

(X - 30) does.
23 edges because a rectangle has 5 edges and 6 vertices, 5 times 6 is 30 subtracted by the number of faces(7) is 23.
-10
If you mean (2/5 times 30) minus (4/3 times 15/8) then the answer is 19/2 or 9.5
which least number should be subtracted from 1000 so that 30 divides the difference exactly
