I'm really sorry, but I only know the first question.
The answer is 340.
Y = 5
x = 4
Multiply both variables by 8/5
y = 8
x = 32/5
Your answer is 32/5
Let k be a constant
y = kx
Plug (20, 4) into the equation
4 = 20k
Divide both sides by 20
k = 1/5
Your equation is
y = (1/5)x
Have an awesome day! :)

Answer:
1. The pin’s location aids to create two drawings simultaneously. This is that while drawing an image, a copy, which may vary in size, is created at the same time.
2. The pantograph relates to dilation and similarity due to the use of similar triangles that affect the scale of the second drawing.
3. The use of similar triangles illustrates the process of the pantograph because the ratio of similitude is set when determining where to place the pin. When a triangle is moved while tracing a line, along with the outline of the image, an enlarged/reduced version of the image is created by the other pantograph's end.
4. The pantograph is now obsolete and has been replaced by several different ways of producing duplicates such as photocopying, mass printing, and digital filing.
As three hours divided by 2 is 1.5 hours, we know that to find how far the person walks in hours, we simply have to double the distance the person walked in 1.5 hours.
2.4*2=4.8
The person walked 4.8 miles in three hours.
Does that make sense?
