Brad says that if a second number is 125% of the first number, then the first number must be 75% of the second number. is he correct? justify your answer.

Given:

A second number is 125% of the first number.

To Find:

Whether the first number is 75% of the second number.

The first number is not 75% of the second number. It is actually 80% of the second number.

Step-by-step explanation:

Let the two numbers be denoted by x and y. Given that y is 125% of x. So,

We can simplify this as

Or,

Thus, we see that the first number is not 75% of the second number. It is actually 80% of the second number.

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.
