An airplane travels at an unknown elevation before it descends 3 miles to an elevation of 15 miles. Find the elevation of the pl ane before its descen.
1 answer:
Answer:
18 miles
Step-by-step explanation:
Let's call it's initial elevation x. Because it descends 3 miles, we now have x - 3. The question says it is now 15 miles above sea level, or x - 3 = 15, and adding 3 to both sides shows that x = 18 miles.

Answer:
Yes, the boats are safe to ride.
Step-by-step explanation:
40 (4) + 12 (2) ≤ 500
160 + 24 ≤ 500
184 ≤ 500
184 is less than 500.
because I was not sure if you had 9 adults instead of 2, this is the answer:
40 (4) + 12 (9) ≤ 500
160 + 108 ≤ 500
268 ≤ 500
268 is less than 500
Answer:
Step-by-step explanation:
(3,4)=x1,y1 (5,8)=x2,y2. The slope is calculated using formula: Slope =y2−y1x2−x1. =8−45−3. =42. =2.
Answer:
3x = -y - 3
divide both sides by 3
x = -1/3y - 1
Answer: 4x = -8
