HELP PLEASE! Robert needs to cut four shelves from a board that is 2.5 meters long. The second shelf is 18 centimeters longer th
IRISSAK [1]
Let us assume the length of the first shelf = x
Then
The length of the second shelf = 2x + 18
Length of the third shelf = x -12
Length of the fourth shelf = x + 4
The total length of the board = 2.5 meters.
                                              = ( 2.5 * 100) cm
                                               = 250 cm
Then we can write the equation as
x + 2x + 18 + x - 12 + x + 4 = 250
5x + 10 = 250
After dividing both sides of the equation by 5 we get
x + 2 = 50
x = 50 - 2
   = 48
Then
The length of the second shelf = 2x + 18
                                                 = 2(48) + 18
                                                 = 96 + 18
                                                 = 116
So the length of the second shelf is 116 cm.
