Answer:
the constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Value of expression 
is 22 .
<u>Step-by-step explanation:</u>
Here we have the following expression to solve :
8÷2*5+(6-4)
⇒ 
⇒
But 8 = 4(2) , So
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, Value of expression is 22 .
Answer: 9 centimeters
Step-by-step explanation:
Add up all the sides, 6 + 10 + 11 = 27,
Since it’s the perimeter of an equilateral triangle, you do
27 / 3 = 9, which is the answer.
