When a number x is multiplied by 4, the result is 2/5 . what is the value of x? drag and drop the correct number into the box so that the equation is true

Note the equation given is:

4(x) = 2/5

Isolate the x. Note the equal sign. What you do to one side, you do to the other. Divide 4 from both sides

4x/4 = (2/5)/4

x = (2/5)/4

x = 2/20

x = 1/10

Check: Plug in 1/10 for x.

1/10 x 4 = 4/10

Simplify 4/10. (4/10)/(2/2) = 2/5 (True)

1/10 is your answer

hope this helps

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.
