Answer:
3200
Step-by-step explanation:
We need to find 2/5 of the tickets sales
2/5 * 8000
you need to find what 2/5 is and the you take that away from 8000 and then you have your answer of 3200
Answer
2x - 7 = 4
14.4775121859299
sinx = 125/500
sinx = 1/4
or, x = arcsin(1/4)
8y = -6
x + 6y -x +2y = 9 +(-15) ➡ 8y = -6
