The answer is:
________________
n = ¼ ; or, write as:
n = 0.25
______________________
Explanation:
__________________
-7 / (2n) = 49 ;
__________________
-49 * (2n) = -7 ;
________________
Divide each side by "(-49)" ; to isolate the "2n" on one side, and to get rid of the "negative" values:
_____________________________
[-49*(2n)] / -49 = -7/ -49 ; to get:
_______________________________
2n = (½); Now, divide EACH side of the equation by "2"; to isolation "n" on one side of the equation, and to solve for: "n";
__________________________________________________
2n / 2 = (½) / 2 ;

To get:

Answer:
Step-by-step explanation:
By Pythagoras Theorem:
Answer:
a:b = 5:4 = 35:28 (multiplying by 7)
b:c = 7:3 = 28:12 (multiplying by 4)
now a:b:c = 35:28:12
