If the question asks for the mean of the alligators
You add all of the number and divide the number you added
(7+0+11+10)/3 = 8
I supposed to divided by 4 here since there are 4 numbers but I considered 0 is just 0 so just divided by 3. I hope this answer will help.
95 + 68,95 = 163,95
6,1% de 163,95 =
(6,1*163,95)/100 =
10,00095 ~ $10,00
11. 2x+3x+1=21
5x+1 =21
5x=20
x=4
TU= 2(4) which is 8
UB= 3(4)+1 which is 13
12. 4x-1 +2x-1=5x
6x-2=5x
-2=-1x
2=x
X=2
TU= 7
UB= 3
TB=10
Problem 13:
2x-8=x+17
2x=x+25
x=25
AB =42
BC=42
AC=84
Problem 14:
3x-31
-x+6
=
2x-37 for BC part now we solve for x
x+6=2x-37
6=x-37
43=x
So :
X=43
AB=49
AC=98
BC=49
the answer is 1.875 pounds
