Answer: The most important aspect in doing algebra is having a pen/pencil and paper in hand. It'll give you a better understanding of the question being posed.
You are correct. You multiply both sides of the second equation by -9 so that the y turns into -9y. That way you add it to the +9y in the first equation to get 0y (the y terms cancel afterward). Nice work.
Out of the choices given, the prediction for the population after 4 years is about 1, 624 deer. The correct answer is B.
Answer:
19°
Step-by-step explanation:
Set up the equation (triangles add up to 180 degrees)(Right angles are 90 degrees).
39 + 90 + 2x + 13 = 180
142 + 2x = 180
2x = 38
x = 19
Using a mile to km converter - 22 mi = 35.4056 km/sec
Multiply 35.4056 and 10
That equals 354.056 km.
