Answer:
7,9,11,13 = 40
Step-by-step explanation:
second number is 9
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.
You would have to divide 5 by 12 then multiply by 30 which gives you $12.50
3 plus 4o hundredths is larger.
1. .412
2. 3.049
