Answer:
350km
Step-by-step explanation:
If a map has a scale of 1: 500000, then 1 cm on the map is 500000 cm
So 7 cm on the map is 35000000 cm = 350 km
What should be my first step when subtracting integers is to .A.add the opposite.
<h3>What are the
step to follow in order to subtract integers?</h3>
To perform this operation first number must be kept as the minuend, and then then change the operation from subtraction to addition.
Then proceed with the regular addition of integers, hence What should be my first step when subtracting integers is to add the opposite.
