1.40+1.80=3.20 or 3.2
5x+32+7x+8=180. By the laws of commutativity we can thus say that 12x+40=180. Subtracting 40 we get 12x=140. Divide by 12 and you get x=(do it yourself) This has nothing to do with calculus by the way.
It is: 126 plus 54 = 180
a + 3a + 5a = 180 9a =180 a = 20
It is: 97+83 = 180
180+72=252
It is: 157+23 = 180
To find the number that plus 150 equals 180, you can set up the equation: x + 150 = 180. By subtracting 150 from both sides, you find that x = 30. Therefore, 30 plus 150 equals 180.
87794 + 39357 + 180 + 439 = 127,770
180
120 + 60 = 180
My answer is 149.50
60 plus 60 plus 60 equals 180 !
