Answer:
C. 
Step-by-step explanation:
We have been given a ratio 16:200 and we are asked to find the ratio as a fraction in simplified form.
Since ratio compares two numbers or two quantities that are measured with the same unit.
Upon converting our ratio into fraction we will get,

Let us cancel out greatest common factor from numerator and denominator of our fraction to simplify it.

After cancelling out 8 we will get,

Therefore, our fraction simplifies to
and option C is the correct choice.
Just use the substitution method for the number 3 into 25= 70n
25= 70(3)
25= 210
Answer is No
So, since y= -7x + 15, and it also equals 5x - 9, you can take what y equals (either one works in this scenario) so lets take the 5x - 9. since this is what y equals, you can take that expression and replace y with it in the other equation. After you do this you'd get 5x - 9 = -7x + 15. Now both sides of this equation are equal to y. To find the solution, you solve for the variable. After you do this, you get x = 2. Now that you know what x is, you can plug that into any of the original equations to find y. lets use y = 5x - 9 again. This time, substitute x with the number you found earlier, 2. Then you solve. It should look like this: y = 5(2) - 9. So y is 1. There is your answer, x = 2, y = 1.

Find the slope
we know that
If two lines are parallel, then their slopes are equal
The slope of the given line is 
so
The slope of the line parallel to the given line is also 
step 2
Find the equation of the line in point slope form

we have
