A cyclist travels at 10 km/hr for 2 hrs and then at 20 km/hr for 1 hr. Find the average speed.

12.5 km/hr

Step-by-step explanation:

You find the mean after making them both the same measurement.

You would divide 10 by 2 to get 5 km/hr

You would use the 20 km/hr

You would add them and get 25

Then divide by 2 to find the mean and get 12. 5

PLZ MARK BRAINLIEST

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

welcome!

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
