Given the equation,D=m/v if D=6/7 and =m+3 then m=.

mamaluj [8]

Answer:

$m=18$

Step-by-step explanation:

The equation given is $D=\frac{m}{v}$

and also we have that $D=\frac{6}{7}$ , thus:

$\frac{6}{7}=\frac{m}{v}$

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

I think the question is missing which variable is defined as $=m+3$ , so I will solve for $v=m+3$ since is the only other variable in the equation.

substituting $v=m+3$ into $\frac{6}{7}=\frac{m}{v}$ :

$\frac{6}{7}=\frac{m}{m+3}$

and we solve for m:

$(m+3)(6)=7m\\6m+18=7m\\18=7m-6m\\18=m$

m is equal to 18.

I don’t understand the word problem.

Remark

The population that is middle class is (4/5) * 2000 * 4/5 = 8000/5 = 1600

The others are 2000 - 1600 = 400 which should be 1/5 of the population.
