C would be your answer i hope i helped you :) sorry if i’m incorrect. i’m not sure
Let the average cost of car in 2009 be $x, then the average cost of a car in 2013 is 2x - 5
25,000 = 2x - 5
2x = 25,000 + 5 = 25,005
x = 25,005/2 = $12,502.50
difference= 0.78[Anastasia's] - (1 - 0.34)[Sergei's]=
0.78m - (0.66m)=0.12m=12cm
Use a system of equations.
(x=# of small dogs, y=# of big dogs)
x+y=9 (times by -5) -5x-5y=-45
5x+8y=51
Then add the equations together and the x's cancel.
3y=6
y=2
So he walked 2 big dogs and 7 little dogs.
Answer:
that is the way of calculating by using synthetic division
