Answer:
c=39
Step-by-step explanation:
4+2=6
To remove square root you have to square everything making the 6 a 36 and then add 3. At the end it is a 39.
Simplify the equation to n-6=4n+18
subtract 4n from both sides
n-6-4n=4n+18-4n
-3n-6=18
add 6 to both sides
-3n-6+6=18+6
-3n=24
divide both sides by -3
-3n/3=24/-3.
n=-8

Answer:
Step-by-step explanation:
I don't do this question the same way as it is done in the classroom, but I will get you the right answer
Let the middle number = x
Let the smallest number = x - 2
Let the largest number = x + 2
x - 2 + x + x + 2 = 315 Combine like terms. The 2s cancel
3x = 315 Divide by 3
x = 105
So the middle number is 105
The smallest number is 103
The largest number is<u> 107</u>
Total 315
This method cuts out at least one step. It works best with an odd number of terms. If you have an even number, you have to use the more traditional method.
