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.
Answer:
Step-by-step explanation:
a)
As given y=mx lets replace mx with y in the first equation
2y=n => y=n/2, replace y with n/2 => mx=n/2, thus x=n/2m
b)
As given y=nx lets replace y with nx in the first equation
x+n^2x=m => x(n^2+1)=m = > x=m/(n^2+1), thus y= n*m/(n^2+1)
c) Replace y with nx => mx-nx=n => x(m-n)=n = > x=n/(m-n), thus y=n^2/(m-n)

Answer:
So, the initial number of apples is 7.
Step-by-step explanation:
The number of apples of An, Binh, and Chi are the same. An gave away 17 apples, Chi gave away 19 apples, so now Chi's apples are 5 times higher than the total remaining apples of An and Binh. How many apples did each of you have at first? (Solve the above problem by equation or system of equations)
Let the initial numbers of apples is a.
An gave 17 apples
Chi gave 19 apples
So,
x - 19 = 5 (x - 17 + x)
x - 19 = 5 (2x - 17)
x - 19 = 10 x - 85
9 x = 66
x = 7
