Answer:
15
Step-by-step explanation:
if point N is located on the line segment MO, then MN + NO = MO. Given the following value of each line segment MN=x, MO=3x-6, and NO=x+1, to get MO, we need to first get the value of x by substituting the given functions into the expression above as shown to have;
x + x+1 = 3x - 6
2x + 1 = 3x -6
collect like terms
2x - 3x = -6-1
-x = -7
x = 7
Then we can get the numerical length of MO by substituting x = 7 into the function MO = 3x - 6
MO = 3(7)-6
MO = 21-6
MO =15
Hence, the numerical length of MO is 15units.
