90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12

2 times 90 equals 180

270

180

90+90=180

To solve this one, subtract 50 from 180 and you'll have your answer.

The result of the equation - 90 plus 90 plus 60 plus 80, is found as follows; 90 + 90 + 60 + 80 = ( 90 + 90 ) + 60 + 80 = 180 + ( 60 + 80 ) = 180 + 140 = 320 Answer = 320
