## lollypopabby43 Group Title A student scored 83 and 91 on her first two quizzes. Write and solve a compound inequality to find the possible values for a third quiz score that would give her an average between 85 and 90, inclusive. (1 point) 85 ≤ ≤ 90; 81 ≤ n ≤ 96 85 ≤ ≤ n; –2 ≤ n ≤ 3 90 ≤ ≤ 85; 96 ≤ n ≤ 81 83 ≤ ≤ 90; 73 ≤ n ≤ 94 one year ago one year ago

Suppose "x" Is the score she got in her third quiz.

2. lollypopabby43 Group Title

3. hba Group Title

Add All The Scores And Divide By number of subjects

4. lollypopabby43 Group Title

so add 83 and 91 then divide by 2?

5. hba Group Title

No Add 81,91 and x and divide by 3

6. lollypopabby43 Group Title

7. hba Group Title

8. hba Group Title

And show it to me :)

9. lollypopabby43 Group Title

11. lollypopabby43 Group Title

okay well you get 57.33X

12. hba Group Title

No Dont Do That ...Show Me The Steps

13. lollypopabby43 Group Title

81+91+X=172X then take 172X/3=57.33

14. lollypopabby43 Group Title

i think

15. hba Group Title

Its 83

16. lollypopabby43 Group Title

screw it i'll just guess thanks for your help

17. hba Group Title

so \[83+91+x/3\]

18. lollypopabby43 Group Title

yeah but thats what all of them say but one

19. hba Group Title

\[174+x/3\]

20. hba Group Title

given average lies between 85 and 90

21. hba Group Title

\[ 85<= 174+x/3<= 90 \]

22. hba Group Title

now multiply whole equation by 3 @lollypopabby43

23. Girly17 Group Title
