Answer:
-12
Step-by-step explanation:
So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).
Then, we need to know the slope-intercept form of an equation. The slope intercept form is
where
is the slope of the line and
is the y-intercept. In this problem where can see the second equation is already in this form.
Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.
To do this, we know we need to make sure
is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have
so we have to divide both sides by
to get 
Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or
in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.
Divide 315,530,612 by 3,539,225 to get 89 people per square mile (rounded)
You times the height,length,and width together and get 168in.3.
The answer shouls be 4.
m is men and f is female, so
