12x/15-10x/15
=2x/15 is your answer
Answer:
2x^2 +15x = 6
Step-by-step explanation:
the form of this equation makes it easier to use the completing the square method
The laws of sines is already indicated in the provided images.
1. sin20/3.3 = sinC/5.4
Thus, angle C is 34.03 degrees. To find angle B: 180 - 20 - 34.03 = 126 degrees. Using the law of sines,
sin20/3.3 = sin(126)/b
b = 7.8 units
From this answer, we can already tell that the answer is letter C: <span>3 units and 7.8 units.
2. Angle J = 180 - 120 - 40 = 20 degrees. Then,
sin(20)/2 = sin(120)/k
k = 5.1 units</span>
Answer:
D) Ashley and Allan live about the same distance from the school
Step-by-step explanation:
1 m = 3.3 ft . . . . . . given
2000 m = 6600 ft . . . . . multiply the above equation by 2000
Since 6600 ft is about the same as 6000 ft, the appropriate choice is D.
