What is the midpoint of line segment ab?

(3, 5.5)

Step-by-step explanation:

We are given a line segment AB and the coordinates of two points: A(-1, 8) and B(7, 3) and we are to find the mid-point of line segment AB.

We know that,

mid-point =

so putting in the values of the given coordinates to get:

Mid-point of AB =

Therefore, the mid point the line segment AB is (3, 5.5).

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

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.
