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
1500m is already in a form with two significant figures.
12x - 2x = 10
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.
