Answer:
Akash walked 
kilometers in all.
Step-by-step explanation:
Given that:
Distance covered while walking to school = 2/3 km
Distance covered while walking back = 3/5 km
We will add the distance.
Total distance walked = 
Total distance walked = 
Total distance walked = 
Hence,
Akash walked kilometers in all.
So y=mx+b
m=slope
y=-3x+b
subsitutue 1 for x and 4 for y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b
the equaiton is y=-3x+7
In numbers, the place values from right to left are ones, tens, hundreds, thousands, ten thousands, hundred thousands...
So for your number, the order is
9 - ones
60 - tens
500 - hundreds
4,000 - thousands.
From the place value you're rounding to all the way to the left, the numbers stay the same.
So your answer is 64,000
