<h3>Answer: 10</h3>
============================================
Work Shown:
First add up all the ages
9+13+9+10+10+9+10+10+11+9 = 100
Then divide that sum by 10, since there are 10 values we added up
100/10 = 10
The average age is 10 years old.
Link is scam dont use it or put it in pls :)))) it’s like. boy
1/3x - 2 = 1/4x + 11....it looks to me like one y was subbed in for another...
ur 2 equations are :
y = 1/3x - 2 and y = 1/4x + 11...but we need them in standard form...
y = 1/3x - 2
-1/3x + y = -2 ..multiply by 3
-x + 3y = -6.....or 3y - x = -6 <==
y = 1/4x + 11
-1/4x + y = 11 ...multiply by 4
-x + 4y = 44 or 4y - x = 44 <==
