Let x = the first even number
x + 2 the second
x + 4 the third
x + 6 the fourth
Add together.
x + x + 2 + x + 4 + x + 6 = 92
Combine like terms.
4x + 12 = 92
Subtract 12 from both sides
4x = 80
Divide both sides by 4
x = 20
Answer:
0.5
Step-by-step explanation:
Since Ashok stays for exactly 15 minutes after his arrival, they will meet if he arrives in the 10 minutes between 9:10 and 9:20 independently of the time Melina arrives.
Since there are 20 minutes from 9:00 and 9:20 and Ashok arrives at a random time, the distribution of his arrival is uniform, so the probability that he arrives between 9:10 and 9:20 is
10/20 = 0.5
It's still 36% because you droppet it and then gain it back up
The answer is b because if you divide that’s what you get
Luke earned $54 for 3 lawns
