A proportional change means that for every change in 1 value, it is accompanied by a change in another value that is the same every time. For example, with this, if x=1 then y=2*1=2. If we move x up 1 value to 2, y=2*2=4. Next, if we move x one more value up then 3*2=y=6. As you may notice, y adds up by 2 every time. In addition, you multiply the x value by the same number every time and only that number (no adding anything) and it is therefore a proportional equation
Answer:
a=3w−y
Step-by-step explanation:
Step 1: Flip the equation.
−a+3w=y
Step 2: Add -3w to both sides.
−a+3w+−3w=y+−3w
−a=−3w+y
Step 3: Divide both sides by -1.
(-a)/1=-(3w+y)/1
a=3w−y

Answer:
Wow! This is hard. I will try i answer it but for now other people will have ze chance
Step-by-step explanation:
A) Yes, it is proportional. This is because, for every 3 cups of dry dog food, there is 1 cup wet dog food added. Starting from 4.5 cups dry dog food, there is 1.5 cup dry dog food added for .5 cups wet dog food, and then there is 3 cups dry dog food added for 1 cup wet dog food.
b) To find the amount of dry dog food added, you multiply the wet dog food by 3:
5.5 x 3 = 16.5 cups dry dog food.
