Answer=7:13

Kenny's Weight*6/7=Melvin's Weight

So, for example, if Melvin's weigh was 7...

Kenny's Weight*6/7=7
divide both sides by 6/7
Kenny Weight=6

So we can say that Melvin's weight to Kenny's weight is 7:6

The boys total weights would be...
7+6=13


So Melvin's weight over the total weight of the two boys is:

7:13

Answer:

\frac{7}{13}

Step-by-step explanation:

Let

x------> Melvin's weight

y------> Kenny's weight

we know that

y=\frac{6}{7}x

x+y=x+\frac{6}{7}x=\frac{13}{7}x -----> total weight of the two boys

Find the ratio of Melvin's weight to the total weight of the two boys

ratio=\frac{x}{(\frac{13}{7}x)} =\frac{7}{13}

P:-3x + 8x - 5x = x<br><br> q: (3x)(5y) = 15xy<br><br> Which of the following statements is false?
Varvara68 [4.7K]

Answer: Statement p is false.

Step-by-step explanation:

In both cases, we need to isolate the variables:

p: -3*x + 8*x - 5*x = x

   (-3*x - 5*x) + 8*x = x

    -8x + 8*x = x

        0 = x

This will be true only for one value of x, so this is not always true, which means that the statement is false.

q: (3*x)*(5*y) = 15*x*y

let's solve the left side:

  3*x*5*y = 15*x*y

  (3*5)*(x*y) = 15*x*y

   15*x*y = 15*x*y

This is true for every value of x and y, then this statement is true.
