0.621371 multiplied by 380 is 236.12.
x=-47.6 ================================== Before the supervisor starts to complain about detail, I'll show that man's work: 380 - 9x = x - 96 380 - 10x = -96 - 10x = - 96 - 380 = - 476 X = + 47.6 . Whoops. I got a different answer. Let's check my solution. Substitute it in the original equation: 380 - 9(47.6) ?=? 47.6 - 96 380 - 428.4 ?=? - 48.4 - 48.4 ?=? - 48.4 Yes ! The first contributor's answer above was wrong by its sign. X = + 47.6
0.621371192 is the number to convert from km's to miles.2679 x .0621371192 = 1664.653423368 1.609344 is the number to convert miles to km's does that answer your question?
380 x 2 = 760
x2 + x = 380 x2 + x - 380 = 0 (x + 20)(x - 19) x = 19, -20
x2+x-380 = (x+20)(x-19) when factored
If 38,000 is 100% then 380 is 1% and 380 x 80 is 80% .... 380 x 80 = 30,400
760
380 x 97 = 36,860
0.70 x 380 = 266
