20 + 10 - 31 + 30 - 5 = 24
32+14+20+18+16+31+21+16=168
1 + 10 + 20 = 31
55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
$31.00 + (20%) = $37.20
It is 31/20 or 1.55
(13+47+31+10+20+50+36+54+122+4)/60==(13+47+31+[10+20+50]+36+54+122+4)/60 =(13+47+31+80+[36+54]+122+4)/60=([13+47]+31+80+90+122+4)/60=(60+31+80+90+122+4)/60=(31+122+4+60+80+90)/60=(153+4+60+80+90)/60=(157+60+80+90)/60=(157+140+90)/60=(157+230)/60=387/606 min. 27 sec.
The sum of 20 added to itself 20 times is calculated by multiplying 20 by 20, resulting in 400. Therefore, the answer to the given equation is 400.
4(3b - 5) < -31 + 12b12b - 20 < -31 + 12b, this is not true because -20 > - 31, so that the solution for the given inequality does not exist.
The mathematical statement 31 plus 31 would have an answer of 62.
20% of 31= 20% * 31= 0.2 * 31= 6.2
5n - 11 = 4n +20 Add '1' to both sides 5n = 4n + 31 Subtract both sides by '4n' n = 31 THe answer!!!!!
