Answer:
4
Step-by-step explanation:
13.50 - 10.50 = 3.00
3 / 0.75 = 4
Answer:
d1= -d2+M
Step-by-step explanation:
you would multiply d1 and d2 by 1/2, then add negative d2/2 to each side, then divide each side by 2/1.
hope it helps

Answer: 
The trick is to realize what your choices are.
if m or n or both are divisible by 5, then 2mn will be divisible by 5
I don't know if you know about x mod(5), but in that case there can only be 4 possibilities for m and n
m mod (5) = +/- 2 or m mod(5) = +/- 1
In the first case m^2 = 4 mod(5) and in the second case m^2 = 1 mod(5) N has the same considerations.
If m and n have the same modular results (both are [say] 2 ) then m^2 - n^2 which be 0
If they are different, then (m^2 + n^2) mod 5 = 0
