Well lets say M=Melvin's weight and B=two boys the ratio would be M:B or
M to B. If it was the ratio of the two boys to Melvin's weight it would be B:M or B to M. Hope that helped!!☺
-0,5=-1/2
-1/2•(-2)=1
The answer is 1
The value of (x-y) is 16
Further explanation:
We have to use the given values to find the value
Given

We will use:

Simplifying by using: 
So,

As we know that x+y=4
Putting the value in equation

Dividing both sides by 4

The value of (x-y) is 16

We can use the quadratic equation to find the two values of x that are roots of the given equation. We must remember that most of the quadratic equations have two roots, however, we could find quadratic equations with just one root or even with no roots, at least in the real numbers.
Quadratic equation:

So,
From the given equation we have:

Substituting it into the quadratic equation to find the roots, we have:

So,

Hence, the correct options are B and C.
