Answer:
N=15
Step-by-step explanation:
Simplify 1/4 (2n-8)
2n-8/4+1/4n=1/2(n+6)
Factor out the common term 2.
2(n-4)/4+1/3n=1/2(n+6)
Simplify 2(n-4)/4 to n-4/2
n-4/2+n/3=1/2(n+6)
Simplify 1/3n to n/3
n-4/2+n/3=1/2(n+6)
Simplify 1/2(n+6) to n+6/2
n-4/2+n/3=n+6/2
Multiply both sides by 6 (the LCM of 2, 3,).
3(n−4)+2n=3(n+6)
7 Expand.
3n−12+2n=3n+18
Simplify 3n-12+2n to 5n-12
5n−12=3n+18
Add 12 to both sides.
5n=3n+18+12
Simplify 3n+18+12 to 3n+30
5n=3n+30
Subtract 3n from both sides.
5n-3n=30
Simplify 5n-3n to 2n.
2n=30
Divide both sides by 22
n= 30/2
Simplify 30/2 to 15.
n=15
n=15

Step-by-step explanation:
Your answer is correct, but you need both the positive and the negative of the square root of 3. You only listed the positive one.
Answer:
~6.5
Step-by-step explanation:
6*6=32 7*7=49 between 6 and 7 and the middle is 6.5
<span>10 + 69 - (-12) + 9 = 79 + 12 + 9 = 88 + 12 = 100</span>
