Answer:

x is the 9 multiple = 9x

Step-by-step explanation:

  • Let x is the numbers of flour tortillas packages
  • Let y is the numbers of corn tortillas packages

=> the total packages : x + y

Given that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16, it means:

<=> [tex]\frac{y}{x + y}[/tex] = [tex]\frac{7}{16}[/tex]

<=> 16y = 7x+7y

<=> 9y = 7x

<=> x = [tex]\frac{9y}{7}[/tex]

since both x and y are integers y is in the form of 7k where k∈N so

x = 9k

So x is the 9 multiple.

Hope it will find you well.
