Step-by-step explanation: R is at -7 and is at 2. Think of how far away -7 is from 2. -7+9=2.
Answer:
55
Step-by-step explanation:
Let x represent the middle integer. Then the smallest is x-2 and the largest is x+2. Your requirement is that ...
(x-2)/(x+2) > 2/3
3x -6 > 2x +4 . . . . cross multiply
x > 10 . . . . . . . . . . .add 6-2x
The smallest integer satisfying this requirement is x=11. The sum of the 5 integers is 5x = 55.
The smallest sum is 55.
Range increases. This is because range is the biggest number minus the smallest number. So when the biggest number is much bigger than the rest of the numbers, the range increases.
