The only thing you can do with this expression is to factor a 5 out of the two terms: we have

15n-20 = 5(3n-4)

Find y, if x = 60.<br> A) 30° <br> B) 35° <br> C) 40° <br> D) 45°
MArishka [77]
The answer is 30°.
Rule: All three sides must add up to 180
°. 
Since A=60 and the side vertical to the angle which is 90° then side C would be C=90° and that adds up to 150°, so you can conclude that angle B is 30°.
I hope I helped!

At what value of x do the graphs of the equations below intersect?
Zarrin [17]

Answer:

x = 2

Step-by-step explanation:

  1. You would find a value of y to plug into either of the equations. For example, I chose the equation 2x - y = 6. When I set it equal to y, I got y = 2x - 6
  2. Now that I know what y is equal to, I plugged it into the second equation to get 5x + 10 (2x - 6) = -10
  3. You then would calculate for x.
  4. Your end result should be x = 2, which is the point that the two equations intersect

This works because the two equations are set equal to each other, making them share a common value between them.

You can also plug both of these equations into a graphing calculator, and on the graph select the command to calculate the intersection.

Hope this helped!
