Kenny went to the movie theater with some friends. while waiting for the movie to start, he noticed that 3/4 of the seats in the theater were filled, and of those seats, 2/5 of them were his friends. if the theater seats 160 people, how many of kenny's friends were in the theater?

48

Step-by-step explanation:

Take 2 divided by five which equals 0.4

Then you take 3 divided by 4 which equals 0.75

Then you take .75 times .04 equals 0.3

Then 0.3 times 160 equals 48

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
