Answer:
A unit rate is the rate of change in a relationship where the rate is per 1.
The rate of change is the ratio between the x and y (or input and output) values in a relationship. Another term for the rate of change for proportional relationships is the constant of proportionality.
If the rate of change is yx, then so is the constant of proportionality. To simplify things, we set yx=k, where k represents the constant of proportionality.
If you solve a yx=k equation for y, (like this: y=kx), it is called a direct variation equation. In a direct variation equation, y varies directly with x. When x increases or decreases, y also increases or decreases by the same proportion.
To find y in a direct variation equation, multiply x by the constant of proportionality, k.
For example: Given the relationship y=7x, the constant of proportionality k=7, so if x=3, then y=3×7 or 21.
Given the same relationship, if x=7, then y=7×7, or 49.

Answer: 4 days (I think)
Step-by-step explanation:
One cat = 150*2 = 300g
Two cats = 600g
600*2 = 1200 (this is the total amount of food they both eat in a day)
5kg = 5000g
1200g/5000g = 4.17
The bag will last 4 days.

Answer:The answer is 40 apples.
Step-by-step explanation:
It takes 10 apples to make a gram of fat. Multiply the 10 apples by 4 grams of fat to find that it takes 40 apples to make 4 grams of fat.
Answer:
n = ( 40 - m )
Step-by-step explanation:
On a particular day, Ricardo drank a total of 40 fluid ounces of water.
If he drank m fluid ounces of water in the morning of that day, then the number of fluid ounces of water he drank the rest of the day is given by (40 - m) fluid ounces.
If n represents the number of fluid ounces water that he drank the rest of the day, then we can write the equation as
n = ( 40 - m )
Therefore, the above equation can be used to find n. (Answer)
