3 km north.
the east and west cancel out and the 5 north being greater than the two south leave you to only have to subtract the 2 south from the 5 north
Let's call the unknown number x.
x+ (50% of x) = 135
x + (0.5x) = 135
1.5x = 135
x = 135/1.5
x = 90
Therefore, the number is 90
I hope this helps. Keep in mind the 1/3 is slope and the 3 is y-intercept.
1.41 x 10^7 you move the decimal over to the left until you have a number between 1-9
it going to be number three
