A bicycle has been marked down by 40% to $120. What was the original price?

$200

Step-by-step explanation:

A mark down by 40% means the current price is 100%-40%=60% of rhe original price

If 60% represents $120 then the original price which was 100% should be represented by unknown value x.

Application of cross multiplication concept

If 60%=$120

100%=x

60%x=100%*$120

Making x the subject of the formula

X=100%*$120/60%=$200

Therefore, the original price was $200

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
