Answer:the mean is 90
Step-by-step
you find the sum of the values then divide them by the amount of numbers in the set
X: represents how many weeks
N: represents books per week
B: <span>represents </span>books she has at anytime
So the recursive formula would be: 100 - XN = B
answer: 105+3x
step by step: times 3 by 35 an then 3 times x
$12.98 each. You would do $56.07 - $4.15. Then divide the answer of that by four.
Hello there! Provided the information, we know that the nearest multiple of 8 and 9 has to be greater than 50. 8 and 9 do not go into 50.
$9 • 6 hours = $54
$8 • 7 hours = $56
There are 60 minutes in an hour, so we can multiply accordingly:
60 minutes • 6 hours = 360 minutes
60 minutes • 7 hours = 420 minutes
Your final answers are:
It will take John 360 minutes to earn $50.
It will take Amber 420 minutes to earn $50.
(P.S. It takes Amber one more hour to earn $50 than it does for John to earn $50.)
Hope this helps!
