If m + 4n = 2n + 8m ; what is the ratio of n to m ?
a) 1: 4, b) 1: -4, c) -4: 1, d) 2: 7, e) 7: 2

m + 4n = 2n + 8m

To answer the ratio, massage this equation around to find ' n/m ' .

Let's subtract 'm' from each side:

4n = 2n + 7m

Subtract '2n' from each side:

2n = 7m

Divide each side by 'm' :
2 (n/m) = 7

Divide each side by 2 :

n/m = 7/2 . . . . . there's your ratio.  That's choice-'e'.

 

Aye bruh i don’t know this but someone else who smarter than us will answer this

500 dollars and its probably more than that
