Answer:
The mean is: 19
Step-by-step explanation:
Add all of those numbers up (133)
Divide it by the total amount of numbers (7)
133÷7=19
You'll set the two expressions equal to 95.
So 2x+119=95
Then 2x=-24
Finally x=-12
58
Between 60 and 55, 5+8=13
Answer: -6
Step-by-step explanation: It changed -6 each round because -6x3=-18.\
Hope this helped!
N= 13*c+8
n=15*c
15c=13c+8
15c-13c=8
2c=8
c=8:2
c=4 children
n= 15*4=60 notebooks
