Answer:
B
Step-by-step explanation:
See when you multiply 3 x 4 or 4 x 3 the answer is the same (is equivalent)
Similarly, -3 x 3 x -4/9 or 3 x -3 x 4/9 is equivalent
Therefore option(B)
$13.73 weekly
54.92 / 4 = 13.73
Answer:

Step-by-step explanation:
GIVEN: Emma started biking to the coffee shop traveling
, after some time the bike got a flat so Emma walked the rest of the way, traveling
If the total trip to the coffee shop took
and it was
away.
TO FIND: how long did Emma travel at each speed.
SOLUTION:
Let the distance traveled by Emma through bike is 
Total time taken when traveled by bike 
Distance traveled through feet 
Total time taken when traveled by feet 
Now,
Total time taken 



Distance traveled through feet 
Hence distance traveled using bike is
and by feet is 
9. The ration of x to y is always the same. So, the ratio of how much Steven charges to time spent babysitting is always the same.
10. The constant rate of change is 6.25 dollars per every hour. (Im pretty sure that’s what rate of change is - if that doesn’t sound familiar tell me and I’ll fix it)
11. y(6.25) = x
Y is the time spent babysitting.
X is the money he will charge at the end.
6.25 is his hourly charge. (you can find that number simply by diving 50/8 OR 31.25/5)
12. Steven would charge $18.75 for three hours. (You get that by multiplying $6.25 by three hours)
Hope that helped! :)

Answer:
y=-2.5x+12.5
Step-by-step explanation:
5y=2x+10
y=0.4x+2
Slope=-2.5
5=-2.5*3+b
b=12.5
