Answer: n = 9</h3>
========================================================
Explanation:
Let's assume that n is not negative. If we tried the smallest nonnegative value, n = 0, then we get
- 30+n = 30+0 = 30
- n/3 = 0/3 = 0
- sqrt(n+16) = sqrt(0+16) = 4
The middle result 0 isn't a natural number. The set of natural numbers is {1,2,3,4,...} which is the set of positive whole numbers.
So we can't use n = 0.
Through trial and error, you should find that n = 9 is the next value we can try such that sqrt(n+16) is a natural number, and so is n/3.
If n = 9, then,
- 30+n = 30+9 = 39
- n/3 = 9/3 = 3
- sqrt(n+16) = sqrt(9+16) = 5
We see that the middle result is now larger than 0 and it's a natural number. The same can be said for the last result as well.
Answer:
41
Step-by-step explanation:
The two angles are vertical angles, so they are the same value.
(4x - 29) = (3x + 12)
<u> +29 +29</u> Moving terms around to solve the problem
4x - 0 = 3x + 41
<u>-3x -3x </u> Moving terms around to solve the problem
x - 0 = 41
x = 41
Answer:
you are right it is 9
Step-by-step explanation:
5 x 3 = 15 so you go 3 x 3 which = 9 :)
