(20 points will get brainliest) the height of a stack of dvd cases is proportinal to the number of cases in the stack. the height of 6 dvd cases is 114mm. write an equation that relates the height (y) of a stack of dvd cases and the number of cases (x) in the stack. what would be the height of 13 dvd cases

Step-by-step explanation:

Given the height of 6 DVD cases, you can know the height of a single DVD case, by dividing the total height, in the number of cases ( for this problem).

Now, knowing the height of a single DVD case (), you can think the expression in this way: If I already know the height of a single case, the height of any number of cases will be the result of multiplying the height of the case by the number of cases I want to stack.

As the problem states, x is the number of cases in the stack, so, multiply the height of a single case for the number of cases (x).

This will result in the expression:

To know the height of a stack of 13 cases, just replace x=13 in the equation you just figured:   , but don't forget the unit is mm, so the final result is 247 mm.

answer: options
