Answer:
9m^2+17m-9
Step-by-step explanation:
Let A be the number of Dimes & B the number of Quarters, the linear equation is as follows:
A.D+B.Q=2.05
So there are 2 dogs to every 3 cats (put into words)
in order to reach 15 total multiply both 2 and 3 by 3
2x3 = 6
3x3 = 9
so there are 6 dogs and 9 cats
Answer:

Step-by-step explanation:
I'm assuming you are trying to find m. In order to do so, you need to get m on one side.
Before doing that let's multiple -2 and -3m by 

add
to both sides

I would get rid of the fraction so I'd multiply both sides by 


divide both sides by -12m

which can be simplified to

ALL UNLESS THAT
IS A POWER
