Answer: 20
Step-by-step explanation:
Since Line l is a segment bisector, we know that AM and MC are equal to each other.
6y-4=2y+12 [subtract both sides by 2y]
4y-4=12 [add both sides by 4]
4y=16 [divide both sides by 4]
y=4
Now that we have y, we plug that into AM.
6(4)-4 [multiply]
24-4 [subtract]
20
Now, we know that AM is 20.
X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
Answer: X = -12
Step-by-step explanation: 1) 12 + x/4 = 9
2) 12 + x/ 2^2 = 9
3) x/ 2^2 + 12 = 9
I hope this helps you
-15+6= -9
-9+6= -3
-3+6=3
add 6
Hope this is correct and hope it helps x
