Step-by-step explanation:
12+ 3x= -24 -3x
Collect like terms
12 +24= - 3x -3x
36 = - 6x
Divide both sides by -6
Therefore, <em>x</em><em> </em>= -6
Answer:
20 days
Step-by-step explanation:
Expected Task duration
= (O + 4 M + P)/6
Where O = best case scenario = 15 days
P = worst case scenario = 25 days
M = Usual scenario = 20 days
Therefore, expected task duration
= [15 + 4 (20) + 25] ÷ 6
= 120 ÷ 6
= 20 days.
Therefore expected task duration is 20 days.
Step-by-step explanation:
If we take 4 as k then
4k = 4(4) = 16 boxes
k + 9 = 4 + 9 = 13 boxes
The answer is: -1.666666667 or -1.6 repeating
