Answer:
about 65 percentage is the correct answer
We first need to convert 3x - 2y = 8 into y = mx + b form.
To do this, we first subtract 3x from
both sides and we have -2y = -3x + 8.
Now divide both sides by -2 and we have y = 3/2x - 4.
Now, we want the slope parallel to this given line.
Since the m or the coefficient of the x term
represents slope, we know this line has a slope of 3/2.
Now, it's important to understand that parallel lines have the same slope.
So the slope of the line parallel to this line will also be 3/2.
Answer:
The length of the river on a map is 
Step-by-step explanation:
we know that
The scale of the map is 
That means
1 cm on a map is 5,000,000 cm on the actual
or
1 cm on a map is 50 km cm on the actual
so
using proportion
Answer:
