Given line LM and point R that lies on line LM, identify the following ratios given that point R lies a/b of the way along line LM, closer to L than M.
LR:LM
RM:LM
RL:RM

I don't understand how to do this, help.

See explanation

Step-by-step explanation:

If point R lies of the way along line LM, closer to L than M, then

Find all needed ratios:

1.

2. By segment addition postulate,

so

3.

then

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

good luck on ur quiz test or homework. have a good day : )
