This question is easier than it seems. If there are 9 consecutive integers with the mean being 16, then 16 must be the median. So just add four on top and four below 16 to give you your range of 9 values, 12-20. 12+13+14+15+16+17+18+19+20=144, 144/9=16. So the mean of the first four numbers is (12+13+14+15)/4= 13.5. If you check, 13.5 is also the median of these four numbers.
Multiply 13 by 3
13 * 3 = 39 miles
Hope this helps :)
i think the answer is(1,0) im not sure
Hello there! x = 66.
x/6 + 4 = 15
This means that since 15 - 4 = 11, x/6 = 11.
Given the two numbers and a variable, we can multiply:
6 x 11 = 66
66/6 = 11
Therefore, x = 66
Hope this helps!
