Answer:

  • Add 1 until you get 3 and 5
  • Bisect 8 until you get 1, then go 1 either side of the middle

Step-by-step explanation:

It looks like you have no requirement that the segments be on the same line, or that one segment is divided into the ratio 3:5.

Perhaps the easiest is to draw a line, mark two points a convenient distance apart, and use your compass to repeatedly copy that length to the end of itself until you have lengths of 3 and 5. Here's one way to do that:

  • Make marks A and B on a line, with A to the left
  • Copy length AB to the right of B and mark the point C (now AC is 2 units)
  • Copy that same length to the left of A and mark the point E (now EC is 3 units)
  • Copy length AC to the right of C and mark the point D (now BD is 3 units, and ED is 5 units)

Segments BD and ED are in the ratio 3 : 5.

_____

Another way to do this is to start with a segment of a length you can consider to be 8 units. Call it AB. Construct the perpendicular bisector, and call the midpoint C. Construct the perpendicular bisector of AC and call the midpoint D. Construct the perpendicular bisector of DC. Its midpoint E divides the segment so that ...

Answer:

20 + 2x = 4x

Step-by-step explanation:

So you are setting the two expressions equal to each other.

buying a membership card  and paying each time looks like this: 20 + 2x where x is the number of times you go to the gym.  20 dollars base then 2 each time you go.

4 each time you go is just 4x

so just set the two equal to each other.

20 + 2x = 4x

If you solve it you will get x = something, which would be the number of times to make the two equal.
