It is: 12.5+8.8 = 21.3 or if you mean 125+8.8 = 133.8
294. To do this quickly, the "trick" is to recognise that 12 + 88 = 100 Then using the laws of commutativity and associativity, 12 + 194 + 88 = 194 + 12 + 88 = 194 + (12 + 88) = 194 + 100 = 294
88
5x+12 = 4x-88 x = -100
-5 + 12 + 5 = 12
The answer is 278. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
88+16=104 you can solve by doing 104-88 to find x
76 plus 54 plus 92 plus 88 plus 76 plus 88 plus 75 plus 93 plus 92 plus 68 plus 88 plus 76 plus 76 plus 88 plus 80 plus 70 plus 88plus 72 equal 1,440
-12
364 + 88 + 88 = 540
-5+7--4+12 = 18
99 + 99 + 88 + 88 + 72 + 72 = 518
5 + 1 + 4 + 12 = 22
