Answer:
There should be 40 stones in the bucket
Step-by-step explanation:
4:3 = x:30
3*10 = 30
4*10 = 40
x = 40
Hopefully that helped.
rate = (47 2/3 km)/(4 1/3 hrs) = (143/3)/(13/3) = 143/13 = 11 km/hr
8 x - 4 (5 - x) = -44
mutiply the bracket by -4
(-4)(5) = -20
(-4)(-x)= 4x
8x-20+4x= -44
8x+4x-20= -44 ( combine like terms )
12x-20= -44
move -20 to the other side
sign changes from -20 to +20
12x-20+20= -44+20
12x= -44+20
12x= -24
divide both sides by 12
12x/12= -24/12
Answer: x= -2
Calculate the amount 1 man can eat per day from the known amounts:
200 kg / 40 days = 5 kg of wheat per day / 20 men = 0.25 kg per man per day.
Now calculate the time it will take 10 men:
10 men x 0.25 kg per day = 2.5 kg per day.
300 kg / 2.5 kg per day = 120 days
