One kilometer is approximately 31/50 mile. what decimal represents this length?

0.62

31X2=62
50X2=100
62 divided by 100 is 0.62

Hope that helps! :)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
