Answer:
3 days will pass
Step-by-step explanation:
work 24×1/3=8
sleep 24×3/8=9

reach up to 24 with sleep
9+9+9=27
which took a little over 3 days
Answer:
see explanation
Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x
Simple actually. The 1000 is the starting price the -20 is the losing of value per week and the w stands for the number of weeks.
