Integer 1 = n
integer 2 = n + 1
integer 3 = n + 2
n + (n + 1) + (n + 2) = 141
3n + 3 = 141
3n = 141 - 3
3n = 138
n = 138/3
n = 46 --(1st integer)
n + 1 = 46 + 1 = 47 --(2nd integer)
n + 2 = 46 + 2 = 48 --(3rd integer)
so the smallest integer is 46
Answer:
1. 9 to the power of 7

4. 3 to the power of 9.
5. 2 to the power of 12.
Step-by-step explanation:
The number in between 2 and 7 is 4.5.
To find this, find the average of 2 and 7. 2+7 = 9. 9/2 = 4.5.
Hope that helped you.
Answer:
A=3.5
B=4.5
C=9.5
Step-by-step explanation:
You can solve A and C with the last two equations through trial and error
then you plug in the solved A into the first equation to solve for B
Let's make a table of the days, and the number of mails sent each day:
Day nr of mails sent
Monday 9
Tuesday ?
Wednesday 13
Thursday 15
Friday 17
In the last 3 days, the number of mails increased each day by 2, so we could make the assumption that on Tuesday, there were 2 mails less sent than on Wednesday.
So, on Tuesday, we assume that 13-2=11 mails were sent.
We check this assumption with the number of mails sent on Monday, and it works again. So, our assumption is correct.
Answer: 11
