You can use elimination to solve systems of equations with 3 equations. I know how to solve systems of equatons with 3 equations, but I use a different process, I don't know how to use the elimination method.
The distance between the points A to B is 899.9 feet. After rounding off the nearest integer we get 900 feet as the final answer.
Given we know that CD is perpendicular to AD.
The distance between CD is 139 feet.
As from points A the boat's crew measure the angle of elevation to the beacon as 6°
therefore, m∠A = 6°
Another time the angle of elevation is measured from point B which is 19°.
therefore, m∠DBC = 19°
tan 19° = CD/BD
BD = CD/tan19°
BD = 136/tan 19°
now for tan 6° = CD/AD (tangent is opposite over adjacent)
AD = CD/tan 6°
AD = 136/tan 6°
AB = AD ₋ BD
AB = 136/tan 6° ₋ 136/tan 19°
AB = 1295.2 ₋ 395.3
AB = 900 feet
hence the distance from point A to B is 900 feet.

Answer:
0.16 pounds
Step-by-step explanation:
Lena paid $18.96 for 3 pounds of coffee.
$1.00 will make (1x3)/18.96= 3/18.96 = 0.1582278481 pounds = 0.16 pounds
Make Sure you distribute first, then go from there
16. C. 0 means it is at sea level. The question is asking about the elevation of each of the places. 1.3 means the elevation is 1.3 km. If I am wrong than the only other possibility is A.
17. C.Our total will come in the beginning : e = . 40,000 is your base salary so he will get 40,000 no matter what. He also gets $200 per car and per is multiplying so 200 • c. That will be added to our base salary and our equation will be : e = 40,000 + 200 • c.
Hoped I helped!
