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:
<=> =
<=> 16y = 7x+7y
<=> 9y = 7x
<=> x =
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.
