To answer the question above, let x be the number of palettes of the roofing material that one elevator trip may carry.
The inequality expression that satisfy the condition above will then be,
195 + 425x ≤ 2,320
Solving for x gives x ≤ 5. Thus, the maximum number of palettes of roofing materials that may be brought is 5.
9x-6-13x=94
-4x-6=94
-4x=100
x= -25
(0.3m )³
note that 0.3 × 0.3 × 0.3 = 0.027, hence
0.027m³ = (0.03m)³
The answer is 24. If you cross multiply witht he eight over top of the twenty-four, and the x (unknown length of shadow) over seventy-two and cross multiply (8 times 72, x times 24) then get 576 = 24x and divide twenty four on both sides, then that should give you the correct answer.
