I'm guessing you're looking for the mean or average? That would be the sum of all the ages divided by the numbers of people
So:
19+8+21+19=67
Divided by 4
67/4= 16.75
Rounded up you get 17
Answer: " p = - 6 " .
___________________________________
Step-by-step explanation:
___________________________________
Given: 14 = - (p - 8) ; Solve for "p" ;
Rewrite as:
↔ - (p - 8) = 14 ;
which is the same as:
-1(p - 8) = 14 ; ;
Divide each side by "-1" ; to get rid of the "-1" ;
{-1(p - 8) } / -1 = {14} / -1 ;
to get:
(p - 8) = -14 ;
Rewrite as:
p - 8 = -14 ;
Now add "8" to each side of the equation;
to isolate "p" on one side of the equation; & to solve for "p" :
p - 8 + 8 = -14 + 8 ;
to get:
p = - 6 ;
which is the answer:
___________________________________
p = - 6 .

Now, let us check our answer:
___________________________________
Given: 14 = - (p - 8) ;
Substitute our solved value: "-6" ; for "p" ; to see if the equation holds true:
___________________________________
14 = - (p - 8) ;
14 =? -(-6 - 8) ;
14 =? -(-14) ;
14 =? + 14 ? Yes!

Answer:
10/3 or 3 1/3
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
0.5(n-4)-3=3-(n+3)
First, you would do the distributive property:
0.5n-2-3=3-n-3
Then you would simplify and then solve.
0.5n-5=-n
-5=-1.5n
n=5/1.5
n=10/3 or 3 1/3

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!
Aritmetic has a common difference
-27 to -12 is a difference of 15
-12 to 3 is a difference of 15
an=a1+d(n-1)
a1=first term
d=common difference
fist term is -27
common difference is 15
an=-27+15(n-1)
84th term is n=84
a84=-27+15(84-1)
a84=-27+15(83)
a84=-27+1245
a84=1218
the 84th term is 1218
