Answer:
2 $
Step-by-step explanation:
let the original price be x
price after 10% discount = 3.60$


The original price of 2 pens is 4$
original price of one pen = 4/ 2
<u>= 2 $</u>
1 - The value of p in the equation is p = 0.
2 - The simplified form of the equation is 3x = 1, the reason behind this is when you do the equation, you get x = 1/3. When you do the equation 3x = 1 you get x = 1/3 as well.
3 - The value of z in the equation is z = 13.
4 - In order to figure out what step he did something wrong on, we first need to solve the problem, the answer we will get is x = 2.
To do this the easy way, we can solve each step, and see what one wouldn't equal 2, which the step he did wrong is Step 2.
So, to do Step 2 correctly, it would be: Step 2 - 12x − 6 = 14 + 2x.

Answer:
C. 3
Step-by-step explanation:
The constant of proportionality is the slope (or rate of change) of the graph.
To find the equation of the graph;
Take points (1,3) and (3,9)
The slope (m) = change in y ÷ change in x
m = 
Taking another point (x,y) on the graph;
m = 
y - 3 = 3x - 3
y = 3x + 0
y = 3x
This can be expressed as;
y ∝ 3x
Which means that as y rises, x rises too but 3 remains the same. The value 3 is the constant of proportionality in this relationship.
100/1.6=62.5 mph
62.5 mph x 2 hours=125 miles
