The difference between set of whole numbers and a set of integers is that:
Whole numbers = {0, 1, 2, 3, 4, 5...}
Integers = {..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...}
If we name contents of the first set as n, in the second set you can have 2n-1 numbers (because we count 0 only once in both sets).

Answer:
The productivity is measured in cubic meters per kilogram.
Step-by-step explanation:
For the formula for the productivity
of the camel

where
is the area of the hump and is measured in square meters,
is the distance the camel can travel (measure in meters), and
is the mass of the camel (measured in kilograms
).
Then, the productivity of the camel is measure in


cubic meters per kilogram.
Answer:
AC=7.5 cm
CB=10.5cm
Step-by-step explanation:
Since we don't know the distance from C to B, we can label it as x. Our equation will be x+(x-3)=18. Simplify that so it is 2x-3=18. Add 3 to both sides and get 2x=21. x=10.5 So AC=7.5 cm and CB is 10.5 cm
