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
It is: 157+23 = 180
180+72=252
87794 + 39357 + 180 + 439 = 127,770
180
120 + 60 = 180
My answer is 149.50
60 plus 60 plus 60 equals 180 !
x = 116. x + 64 = 180 is the same as x = 180 - 64, which equals 116.
