The constant of variation is 10/3.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
y ∝ x
This can be written as an equation as,
y = kx
Where k is the constant of variation.
Now,
When x = 3, y = 10.
10 = 3k
k = 10/3
Thus,
The value of k is 10/3.

the answer will be -19n+25. All you do is put 19 into the g spot and distribute from that point on into the parentheses. so -19 to n and multiply -19 and -1. after that you get -19 +19+6. you will then add like termsso 19 and 6 is 25. Final answer is -19n+25. Hope its right. Good Luck !
