7/16 + 5/8
find a common denominator:
7/16 + 10/16
17/16
otherwise written:
1 and 1/16.
(7a=3)=(-a-5)=16
1/5+1/11 = 11/55+5/55 = 16/55
1 and 2/5
-2x + 3y = -7 3x + y = 16 simultaneous equations. Elimination a letter. Arbitrarily select 'y' Hence multiply the bottom eq'n by ' -3' Hence -2x + 3y = -7 -9x - 3y = -48 Add the eq'ns/ -11x = =55 x = -55/-11 = 5 When x = 5 , substitute into either eq'n for 'y' -2(5) + 3y = -7 -10 + 3y = -7 3y = 3 y = 1 Hence answer in ( x,y) fpr, is ( 5,1).
(11, 5)
no, 5.
144 9+7 = 16 and 9*16 = 144
5/16 + 5/14 + 5/16 =10/16 + 5/14 = 140/224 + 80/224 = 220/224 = 55/56
5/16 + 5/4 = 25/16 or 19/16
v=5
1 over 3 plus 1 over 12 equals 5 over 12
144 9+7 = 16 and 9*16 = 144
