Answer:

Step-by-step explanation:

v=d/t, t=d/v, since t=t

1225/(v+w)=1100/(v-w)

1225v-1225w=1100v+1100w

2325w=125v

w=125v/2325, given v=575

w=125(575)/2325

w=30.91 mph

Explain how you would estimate to subtract 189 from 643
bulgar [2K]
To estimate an answer to this problem, you must first estimate the numbers as well. 189 would round to 190, and 643 would round to 640. Now you would subtract 190 from 640, giving you 460.

Jordan prepares 200 name tags to use at a meeting. The number for each color of the name tag is described below.
nadya68 [22]

Answer:

The answer would be A. 55.

Step-by-step explanation:

For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.

For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.
