The temperature in a town is 36.6°F during the day and -12.6°F at night. What is the
temperature change from day to night?

43.2°F

Step 1: Get from -12.6°F to 0.

-12.6°F + 12.6°F = 0

Step 2: Go from 0 to up to 36.6°F.

36.6°F - 0 = 36.6°F

Add 36.6°F and 12.6°F together.

36.6 + 12.6 = 43.2

Answer = 43.2°F

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
