Jake's family is moving to a new home. They packed 22 boxes in LaTeX: 1\frac{5}{6}1 5 6 hours. What is the average number of boxes they packed per hour?

12 boxes per hour.

Step-by-step explanation:

Jake's family packed 22 boxes in 1 5/6 hours (that is, 1 hour plus 5/6 of a hour: 1 + 5/6 = (6+5)/6 = 11/6 hours).

So, to know the average number of boxes packed per hour, we can do a rule of three: If in 11/6 hours they packed 22 boxes, in 1 hours they packed X boxes.

22 boxes -> 11/6 hours

X boxes -> 1 hour

22/X = 11/6

X = 6 * 22 / 11 = 12

So, they packed an average of 12 boxes per hour.

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
