Let us assume here, in this situation that each page has the same weight so if i want to find the weight of the complete stack, i will multiply the number of sheets of paper by the weight of a single sheet of paper.

Help! In parallelogram LMNO below, find the length of MO
pashok25 [27]

Answer:

Step-by-step explanation:

The diagonals of a parallelogram bisect each other.

5y - 8 = 3y + 1              Add 8 to both sides

5y = 3y + 1 + 8             Subtract 3y from both sides

5y - 3y = 9                   Combine

2y = 9                          Divide by 2

2y/2 =9/2  

y = 4. 5

5y - 8 =

5(4.5) - 8 =

22.5 - 8 =

14.5

That represents 1/2 of MO

MO = 2 * 14.5

MO = 29
