Best ResponseYou've already chosen the best response.184 divided by 7 equals +12 +12 is your ratio you need to put the x value you know into the ratio 1 times 12 equals 12 so thats the answer but you need to remember to use the ratio to find it otherwise you can end up with the wrong sign or if x had been 2 you would have a completly different answer.
