Find the consecutive odd integers that have a sum of 9. order them from least to greatest
ikadub [295]

Hello from MrBillDoesMath!

Answer:

No solution is possible using odd consecutive integer

Discussion:

Let "n" be the smaller odd integer. Then

n + (n+2) = 9 =>

2n + 2 = 9 =>

2n = 7 =>    Oops!  2n is an even integer; 7 is odd. NO integer solution exists


Regards,  

MrB

(10 POINTS AND BRAINLIEST FOR BEST)
Naddik [55]

Answer:

C. II only

Step-by-step explanation:

Basically all you need do is plug these answers in and if the complete the inequality to make a true statement.

Yes i know no body want to do that but that whats need to be done lol.

once i plug 7 12/7+8 = 12.83

12.83>20

is incorrect

so we need continue

7*2.5+8>20

7*2.5= 17.5

17.5+8= 25.5

25.5>20

this a true statement

so we know 2.5 is an answer

now we need plug in -3

7*-3= -21

-21 +8 = -13

-13>20

this is incorrect
