Let the two numbers be x and y.
The difference between the numbers is 4. Therefore
x - y = 4 (1)
The sum of one-half of each number is 18, therefore
x/2 + y/ 2 = 18
x + y = 36 (2)
Add equations (1) and (2).
(x - y) + (x + y) = 4 + 36
2x = 40
x = 20
From (2), obtain
y = 36 - x = 36 - 20 = 16.
Answer: The two numbers are 16 and 20.
Answer:
C
Step-by-step explanation:
It needs to be an "or" inequality because it is one or the other, not both. The reason C is correct is because the number needs to be between 4 and 6 or 8 and 10, so greater than the former but still less than the latter.
