The opposite of 5 would be -5, because negative is opposite of positive. Hope this helps!:)
If m1=50 then m=50 so, m3 would be 150 because 50×3=150
It would take 2.61 hours to fly from Dallas to Boston at 775 mph.
Since the time it takes to fly from Dallas to Boston varies inversely with the speed of the plane, to determine, if the trip takes 4.75 hours at 427 mi / h, how long would it take at 775 mi / h, the following calculation must be performed:
- (427 x 4.75) / 775 = X
- 2028.25 / 775 = X
- 2.61 = X
Therefore, it would take 2.61 hours to fly from Dallas to Boston at 775 mph.

Answer:
Step-by-step explanation:
(2d + 1)(3d - 1)
2d(3d - 1) + 1(3d - 1)
6d^2 - 2 + 3d + 1
6d^2 - 1 + 3d
6d^2 + 3d - 1 (after arranging in standard form)
First 17-8=9 then 2•9=18 ,6+18+12=36 then 5•36=170
