weight of package $=192$ pounds

total weight $=205$ pound

$x+192=205$

The table shows the change in the water level (in centimeters) of a reservoir for three months.

dem82 [27]

Answer:

- 1 5/24 cm

Step-by-step explanation:

We'll have to get the fractions to a common denominator. the least common denominator for 3 and 80 is 240.

So - 1 1/3 = - 1 80/240 = 320/240

21/80 = 63/240

-11/80 = -33/240

-------------------------------------

-320/240 + 63/240 - 33/240 = -290/240 = - 1 50/240 = -1 5/24 cm
