THIS IS DUE TMR SO PLEASE HELP WILL MARK THE BEST AND ALSO WILL DONTATE EXTRA POINTS!

Step-by-step explanation:

Sammie is x Jennie is 9 years younger than him. So, Jennie ( y) = x-9

According to second condition eq is

(X-5) = 4(y-5)

Place the value of y in eq 2

You will find x= 17

Put x in eq 1

Y = 8

Jenny is 8 and Sammie is 17

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

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.
