Answer: D. About 
inches per hour.
Step-by-step explanation:
1. The city received 
inches of rain in 
hours.
2. Let's write the mixed number as decimal numbers:
3. To find the approximate rainfall rate in inches per hour, you must divide 12.25 inches by 25.5 hours, as following:
4. If you round the result to the nearest tenth, you obtain:
5. Therefore, the answer is the option D.
Let's set up an equation:
x plus y is greater than 12
x + y > 12
One of the integers is ten less than twice the other one
x = 2y -10
Time to start solving:
(2y-10) + y > 12
2y + y > 12 + 10
3y > 22
3y=24
y=8
Now its time to find the value of x:
x=2(8) - 10
x=16-10
x= 6
6 + 8 > 12, 6+8 is greater than twelve.
In conclusion we can wrap up that 6 and 8 are the least value integers.
1 - TRUE
2 - FALSE
3 - 6 or 14
4 - d/t=r
Option C.
No matter how much n decreases, -1 will always be bigger than 9n.
