Aboard, 75 cm long is cut into three pieces such that the second piece is twice as long as the first and the third is 5 cm longer than the second. find the length of the shorter piece.

First piece = x ; second piece = 2x ; third piece = 2x + 5

x + 2x + 2x + 5 = 75

5x + 5 = 75

5x = 70

x = 14 cm < shortest piece

2x = 2(14) = 28 cm  < shorter piece < Answer

2x + 5 = 2(14) = 5 = 33 cm < short piece

they would have to work 32 hours.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
