Do 9+4 because you need to get m alone. you get 13 plug 13 in for m (13-4=9) and then 9=9
Hans would take 13.5 seconds to run 50 meters
Priya would take 12 seconds to run 50 meters
--------------------------------------------------------------------------------
Since they each ran 10 meters for a certain amount of time you would multiply the seconds by 5 since 10x5=50
When you do that you get
13.5 for Han's time by multiplying 2.7x5=13.5
and
12 seconds for Priya's time by multiplying 2.4x5
20%=20/100
(20/100)*50= 10 pages
Answer:
68 weeks
Step-by-step explanation:
1 week costs $11.50.
so, how many such weekly each cycles fit into the price of new machines ?
if they wait to long (to many weeks) they spend in total more money than buying a new machine.
but if they stay still below that max. number of weeks, they have at least the illusion that they are cheaper of with the weekly laundromat investment (but they forget, sooner or later they will need the new machines).
so the break even point is simply
782 / 11.5 = 68 weeks.
after 68 weeks it has cost them exactly the same amount of money, as if they had bought new machines right away at the beginning.
Since the line is going from the top left to the bottom right, the slope is negative so A and B are possible answers.
the line crosses the y axis at -1
B is the option that ends with -1
therefore your answer is B. y = -2x - 1
