Let x be he length of middle piece.
3x = length of longer piece.
x-5 = length of shortest piece.
x + 3x + x-5 = 40
5x - 5 = 40
5x = 45
x = 45/5
x = 9. ( Size of middle piece )
Given that the longer piece is 3 times the size of middle piece,
Longest piece = 3 x 9 = 27.
Size of longest piece = 27 feet
Size of middle piece = 9 feet
Size of smaller piece = 40 - (27+9)
= 40 - 36
= 4 feet.
Thank you.
Well i did this in my notes and i found this
4m + 23 + n
p + 3
Convert variables to their numbers
4(7) + 23 + 2
8 + 3
Simplify the expression
1. 28 + 23 + 2
8 + 3
2. 51 +2
8 +3
3. 53
8 + 3
4. 53
11
5. 53/11 = 4.82
