Shes is wrong because 30% of 80 is 24
Nellie has to calculate the price per pound for every bag.
1) 2.52 / 3.5 = 0.72 $/lb
2) 5.40/7.5 = 0.72 $/lb
3) 7.92/11 = 0.72 $/lb
Then, price per pound is the same for any bag. There is no advantage of purchasing one or other, given that she can store any quantity.
0 - (-x + 10)
a negative subtracted from something is a positive.
0 + x - 10
Your answer is x - 10
Hope I helped!
Let me know if you need anything else!

An equation of the form y=ax+b, where y and x are variables, and a and b are constants, is called a linear equation.
The reason it is called linear is because the graph of the equation is a line.
The line passes through the origin only if b=0, as in our problem.
Any line (except vertical lines) represents a proportional relationship in that the change in y is proportional with the change in x. It is not a condition that the line passes through the origin.
In our specific case, y=(1/5)x, means that the change in y is always 1/5 of the change in x. That is, if x changes by 5 units, y changes by 1. If x changes by 10 units, y changes by 2, and so on.
So, the constant of proportionality is 1:5, or 0.2.

Step-by-step explanation:
The measure of angle X would be 50 degrees because 65 degrees is already labeled and B would also be 65 degrees so 65 + 65 = 130, and finally subtract 180 - 130 to get the final measure of angle X: 50 degrees
