The answer is 67.5. The other part I do not understand.
You add like terms, which means add the values with the x value, and the values with the y value, and never mix them. So for the x values, you have 4x + 2x, which equals 6x. Then you add the y values, 4y + 6y to get 10y. Then you add them to the remaining 6, and get
5x + 10y + 6
Notice the picture below
recall the "inscribed angle theorem"
now... notice your picture, "x" is just the intercepted arc
Answer:
12/7
Step-by-step explanation:
To set up a ratio of "thing 1" to "thing 2", build a fraction with "thing 1" on top (numerator) and "thing 2" on the bottom (denominator).
The ratio of in-state students to out-of-state students is
and this can be simplified ("reduced") by dividing both numbers by 9 to get the fraction 12/7.
