Yasmine's mother is four time as old as her Yasmine's sister is Ten years older than her
Find an expression in term of k for the sum of their ages, where k representatif Yasmine's age​

Let's take Yasmine's age as 'k'.

(1) Given that, Yasmine's mom = 4 times as old as Yasmine = 4k (keyword ⇨ times = multiplication)

So, Yasmine's mom = 4 × k

____________

(2) Given that, Yasmine's sister = 10 years older than Yasmine = 10 + k (keyword ⇨ older than = addition)

So, Yasmine's sister = 10 + k

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.

step-by-step explanation:
