I think the answer is 1,683.5 ounces.
(481/2=240.5, 240.5×7=1683.5.)
60t +60 = 80t
subtract 60t from both sides of=
20t = 60
t = 3
The two trains are the same distance from Chicago at 3pm, at that time both trains will have covered 240 miles
You can name Plane P, many different ways,
Assuming you are asking this out of a textbook staring at a figure of a Parallelogram, their are probably points inside that shape and the way you would name it would be naming using any three points in the plane that are NOT on the same line in any order. <span />
The answer is 8i.
i = √(-1)
√(-64) = √((-1) * 64)
= √(-1) * √64
= i * √8²
= i * 8
= 8i
Well the LCM (lowest common multiples) for 8 and 32 would be 4. So plug 4 into "b" -8×4-32. -8×4=32. -32-32. Since you can't subtract 32 and 32 you add! Which gives you -64.
Hope this helps (:
