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:
(-4,-4)min, x-intercepts (-2,0) (-6,0), y-intercept (0,2)
Answer:
6/30 for a multiple of 3 and 4/20 for a multiple of 5
Step-by-step explanation:
If each lap is 440 yards, Francesca walked 115 yards per minute.
Answer:
easy :) answer is 12x-8y
Step-by-step explanation:
all you do is combine like terms
1. the 10x + 2x which is 12x
2. (this part gets tricky) you have a NEGITIVE 5 minus 3 so if you are subtracting by a negitive number you add (5+3=8) and keep the negitive (-8y)
