There are 8 math classes in 7th grade.
seven are equally sized and the 8th class
has 32 students. if there are a total of 221.
students in the 7ih grade, how many are in
each of the equally sized math classes?
nova
equation
solution

27 in each of the 7 classes

Step-by-step explanation:

First you would subtract 32 from 221

221 - 32 = 189

Then you would divide 189 (the total remaining students not in the 8th class) and divide by 7 (the total of classes remaining with equal students)

This will give you 27

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
