You can put this solution on YOUR website!
just go one by one and solve each.
A. 20%2Fn=5 then n must equal 4. Next equation,
n%2F5=4
4%2F5 does not equal 4 so
A is FALSE
B. 20-n=5 then n must equal 15. Next equatoin,
n%2F5=4
15%2F5 does not equal 4 so
B is FALSE
C. 5%2An=20 then n must equal 4. Next equation,
n%2B5=25
4%2B5 does not equal 25 so
C is FALSE
D. 20%2Fn=5 then n must equal 4. Next equation, doesn't really make any sense. 20%2F5%2Bn That is not an equation.
since all A, B, and C were false, this one must be true, but I can't prove it because I can't work with that equation.
From my previous explanation, I'm sure you can figure it out. :D
