Answer:
Step-by-step explanation:
<u>Find b first:</u>
- b = 3/x + 3/y
- b = (3x + 3y)/xy
<u>Find 1/b:</u>
- 1/b = 1 : (3x + 3y)/xy
- 1/b = xy / (3x + 3y)
Its 181.3 u just put p and r
It can fly 106*15 = 1,590 miles in 15 hours.
x + x + 2 + x + 4 <= 126 (where x is the first of the numbers)
3x <= 120
x <= 40
So the numbers are 40 , 42 and 44.
