Answer:

A: 40 degrees

Step-by-step explanation:

Since every triangle is 180 degrees, you can start off by subtracting 50 from 180 since that side does not contain a y for you to solve.

Since the other two sides do have a y in them, you would set 130 degrees equal to y+10 and 2y:

130=y+10+2y

Then you would isolate the y's by subtracting 10, and you would add y and 2y together to get:

120=3y

Finally, you would divide 120 by 3 to get your answer, 40=y.

Hope this helps!

Answer:

Between (-6,0) and (-5,0).

Step-by-step explanation:

When it crosses the x axis, it's an x-intercept. To find the x-intercept, set y (aka f(x)) to zero. The solutions to the equation are approximately 3.36 and - 5.36. Since you're finding the negative x-intercept, you only need the negative solution - 5.36. This is in between (-6,0) and (-5,0).

well, if Nathan has 15 million dollars and buys 2 bags and 3 books and if each bag is 2 million you would do 15 minus 2 and when you get the answer you would minus 10 dollars off of that and then do 10 times that number.

I hope you understand what I'm saying if not pls ask for help.
