Jackie runs and dances for 75 minutes every day. She dances 25 minutes more than she runs.

x + 25 = y and x + y = 75
Jackie spends 25 minutes running every day;
X + (x + 25) = 75
-25 - 25
2x = 50
/2 /2
x = 25

25 + 25 = 50 = y
25 + 50 = 75
x = 25 y = 50

What is the greatest amount of time she could spend dancing every day,
given she will take a run.

7

step-by-step explanation:

the answer would be 7

42.4

step-by-step explanation:

convert to decimal

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.
