Astudent scored 81 and 93 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.

To have an average in between 85 and 90 he has to have a total in-between 255 and 270.her current total is 174 so her third score must be 81≤x≤96

I hope this helps.

The decimal expansion would be .27 repeated

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
