Step-by-step explanation:
The ratio and proportion is the mathematical concept that can explain the correlation between the size of a dog and the amount of food it eats. For example dogs weighing 3 to 7 kg should consume 67 to 112 grams of food per day, that is, the amount of food must be proportional to the weight of the dog.
The ratio and proportion are interconnected concepts that allow the understanding of comparison between quantities.
The answer is 4 because on the y-intercept the line hits 4
Answer:
x= -7
Step-by-step explanation:
You need to first add 5 to the -5. Even though the - is a subtraction sign, you can still count it as a subtraction sign. In order to balance it out again, so you add the 5 to the 16. 16+5=21, so the equation would be -3x=21. To get x by itself, you divide by -3. So, -3x/-3 and 21/-3. That gets rid of the -3, and you get a -7 as an answer.
To convert a ratio to a percentage you have to divide then multiply by 100!
