Answer:
a ≤ 20/3
Step-by-step explanation:
Subtract 4 from both sides, obtaining:
-3a ≥ -20. Dividing both sides by -3, we get a ≤ 20/3.
Note that because this is an inequality, and because we've divided all terms by a negative number, we must change the direction of the inequality symbol from ≥ to ≤.
Answer:
5
Step-by-step explanation:
We are being asked in how many ways an enumerated ball can be removed without any type of replacement, therefore it would be a combination without repetition:
nCr = n! / r! * (n-r)!
n, total number of balls, 5
r, specific number of balls, 1
5C1 = 5! / (1! * 4!) = 5
Therefore there are 5 ways to do the above.
Answer:
The average number of daily miles traveled by these individuals was 11.72 miles per day.
Step-by-step explanation:
Given that in 2004, Pen Hadow and Simon Murray walked 680 miles to the South Pole, and the trip took 58 days, to determine the average number of miles traveled per day by these individuals the following mathematical calculation must be performed:
680/58 = X
11.72 = X
Thus, the average number of daily miles traveled by these individuals was 11.72 miles per day.
Answer:
Infinite Solution!
Step-by-step explanation:
First, We simplify the right side.
Distribute -4, -4x-20=-4x-20
Now we add +4x to both sides, now the equation stands as -20=-20
We know when the solution is same #= same #. We have infinite solution!
Answer:
2 miles
Step-by-step explanation:
15 miles - 9 miles = 6 miles
12 laps / 6 miles = 2 miles
