The one u clicked one is the answer ?
Based on the given situation above, the given values are 8 kilometers and 24 minutes. To simplify these values, we will come up with the result of 1 km in 3 minutes. Therefore, the winner of the New York marathon ran 0.33 kms per one minute so the runners unit rate is 0.33kms/minute.
X = pens and y = pencils
4x + 7y = 13.25
y = 0.75
4x + 7(0.75) = 13.25
4x + 5.25 = 13.25
4x = 13.25 - 5.25
4x = 8
x = 8/4
x = 2 <===so each pen cost 2 bucks
Okay, I got you...
2) 2
3) 6
4) 33
5) 5
6) 19
No. (12+6)/2=9
and 12+6/2=15
This happens because in order of operations parentheses come first, so you would do that and get 18. Then you would divide 18 by 2 and get 9.
On the second one you would do division first (6/2) and get three, the you would add 12 and end up with 15.
Hope this helps :)
