48+56=104; 170-104= 66. The librarian needs to pack 66 more books.
Answer: Average or Mean
Step-by-step explanation:
The center of measure calculated was the average or mean. To get the mean of a set of numbers, we have to add all the numbers given and then divide them by the numbers.
In this case, the mean of 3,7,11,11,16 will be:
= (3 + 7 + 11 + 11 + 16) / 5
= 48/5
= 9.6
I think it would be 1462 yards
4y/3 - 3/4 + 5/6y (multiply by) x 2 + 4
4y/3 - 3/4 + 5y/3 + 4
collect like terms: (4y/3 + 5y/3) + ( - 3/4 + 4)
simplify: 3y + 13/4 <----- FINAL ANSWER
(x) + (x + 2) = 58
2x + 2 = 58
2x = 56
x = 28
The two numbers are 28 and 30.
Hope this helps!
