Find 4 consecutive odd numbers with a sum of 80?

17, 19, 21 and 23

Step-by-step explanation:

Let x-3, x-1, x+1 and x+3 be 4 consecutive odd numbers.

Now,

According to question, their sum is 80.

x-3 + x-1 + x+1 + x+3 = 80

4x = 80

x = 20

Four consecutive odd numbers are,

x-3, x-1, x+1 and x+3

20-3, 20-1, 20+1 and 20+3

17, 19, 21 and 23

i dont know sorry

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.
