Reptile [31]3 years ago

Answer: I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D

Which equation results from adding the equations in this system? 11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18.
densk [106]

Answer:

7x = -35

Step-by-step explanation:

11x -3y = -17

-4x + 3y = -18

Add the two equations together

11x -3y = -17

-4x + 3y = -18

--------------------------

7x + 0y = -35

7x = -35

You are given two variables, already declared and assigned values, one of type double, named totalWeight, containing the weight
Alchen [17]

Answer:

double singleWeight = totalWeight/quantity;

Step-by-step explanation:

Considering you already have two different declared and assigned variables, in C language you would have the following lines:

#include <stdio.h>

int main()

{

   double totalWeight = 5.2 ;

   int quantity = 2;

   double singleWeight = totalWeight/quantity;

   

   // Displays operation      

   printf("%f / %d = %f", totalWeight, quantity, singleWeight);

   return 0;

}

It is very important to keep in mind that the type of variable of singleWeight is double due to the expecting number is the result of the division where the dividend is double too.
