Answer:

Step-by-step explanation:
Given expression as:

We need to simplify the given expression.
Solution:
We have:

Rewrite the expression as:

is a common factor to the first two terms.
Using distributive property we can factor out
from the first two terms.




is common factor, so we can factor
from the above expression.




Therefore, we get simplified answer as.

Answer:
I'm not 100% correct but this is what I believe proportionality is where k=y/x and k is proportionality constant
$6.57: 3 pounds of orange
y dollar: x pounds of orange
so the proportion
$6.57 y
_____ = _____
3 x
6.57×
_____ = y
3
2.19x = y
so k = 2.19
Solving for x is easier if
First, remove the parenthesis.
-3(x-1) = 3(4-x)-9
-3x + 3 = 12 - 3x - 9
Next, group the numbers with x on the left side and the rest on the right side.
-3x + 3x = 12 - 9 - 3
0 = 0
So, x has no solution.
