Answer:
y=10x+30
Step-by-step explanation:
x= number of dogs walked
All you have to do is move the denominator on the other side, by multiplying.
a-10
------- = -9
20
multiply 20 x -9
= -180
then it becomes a-10=-180
+10 +10
a=-170
Do 12/16 which equals 0.75
0.75 is equal to 3/4
so the answer is 3/4
Hope this helps!
