It is 110
2d + 25 = 55Therefore 55 - 25 = 2dTherefore, 2d = 30d = 30/2Therefore, d = 15
(6 hours 30 minutes) + (55 minutes) = 7 hours 25 minutes
55/30 =125/3055/30:= 55÷30= 1 remainder 25= 1 25/30
25. 55 minus/subtract/take away 30 = 25.
30 + 25 + 15 + 25 = 95
Assuming you mean 5/14 + 6/12.... 5/14 = 25/70 and 6/12 = 30/70... 25+30=55... 55/70 simplifies to 11/14
cos(30)cos(55)+sin(30)sin(55)=cos(30-55) = cos(-25)=cos(25) Note: cos(a)=cos(-a) for any angle 'a'. cos(a)cos(b)+sin(a)sin(b)=cos(a-b) for any 'a' and 'b'.
The answer is 55. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
