Answer:
29
Step-by-step explanation:
You need to find the average number of students

29
The average is 29
Answer:
the answer its 44=0
Step-by-step explanation:
18y-6y+22=11(y-2)+y1
We move all terms to the left:
18y-6y+22-(11(y-2)+y1)=0
We add all the numbers together, and all the variables
12y-(11(y-2)+y1)+22=0
We calculate terms in parentheses: -(11(y-2)+y1), so:
11(y-2)+y1
We add all the numbers together, and all the variables
y+11(y-2)
We multiply parentheses
y+11y-22
We add all the numbers together, and all the variables
12y-22
Back to the equation:
-(12y-22)
We get rid of parentheses
12y-12y+22+22=0
We add all the numbers together, and all the variables
44=0
are not solution for this equation
Hope helps you and have a great day !
