Answer:
A number is positive if it is greater than or equal to zero. A number is negative if it is less than or equal to zero.
The answer is 110 because if you multiply 8•16=128 and 18 cars are used, you subtract 128-18 which is 110.
If Ike does not want more than 20 pounds in his backpack, this means he wants less than or equal to 20 pounds in his backpack. Because each paper costs 1/3 pound, this can be used as the rate of change and we can set up the following inequality:
1/3x < 20
To solve this inequality, we should divide both sides of the equation by 1/3.
x < 60
Because this inequality means that x is less than or equal to 60, the answer is that Ike can carry 60 papers in his backpack.
Hope this helps!
