<span>Ratio!
Two different numbers are considered proportional if they have the same ratio.
Let’s have an example:
=> I the price of an apple is 2 dollars,
=> then the price of 10 apples are 20 dollar
=> the price of 100 apples are 200 dollars
=> the price of 150 apples are 300 dollars.
And so on…. As long as their values are related, they are proportional.
another example:
=> my hair grows 5 inches in 1 month
=> it grows 10 inches in 2 months</span>
Would this be the correct answer? If not, can you further explain the question?(11x+8y)(11x-8y)
9x = 27
x = 3
y = -1
The answer is (3, -1)
