Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x determine the numerical length of MN

Answer : MN =

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

(segment addition postulate)

(substitution)

Solve for x

Divide both sides by 9

MN = 4x

plug in the value of x

MN = 4(1) = 4

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
