6-2kx=5-2x 2x-2kx=-1 x(2-2k)=-1 x=-1/(2-2k)
5k
2k means 2 thousand
1% of 1500m = 1500m * 1/100 = 15m
My understanding is that 2K means 2,000, like 1K means 1,000 and so on. Also .2K means 200 and .1K means 100.
0m
1500m = 150000cm so it is more
if you mean 2x-1*3 then the answer is: 2x-3
If you mean: -2x+8+20 then it can be simplified to 28-2x
12x - 2x = 10
1500m is already in a form with two significant figures.
If it is 1500m, then it is 1500m, no matter how long the track is. If you mean how many laps, that would be 3.75 laps on a 400m track, and 7.5 on a 200m track.
