The world’s fastest train travels about 162 mi/h. estimate how far the train travels in 4.75 h.

770 miles

Step-by-step explanation:

The world's fastest train travels about 162 miles per hour.

The speed of train = 162 miles/hour

Train travels in 4.75 hour = 162 × 4.75

                                          = 769.5 miles ≈ 770 miles

The train travels almost 770 miles in 4.75 hours.

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
