Distributive property says a(b+c)=ab+ac so
4(3x+2)=4(3x)+4(2)=12x+8
then add
12x+8-2
12x-6
it could also be 6(2x-1)
factor 20b-16
find the greatest common factor of both
20=2 times 2 times 5
16=2 times 2 times 2 times 2
GCF=2 tiemes 2=4
20b-16
undistribute 4 from each (divide each by 4)
4(5b-4)
Answer: 8.7 the mean is 20
Step-by-step explanation:
Answer:
3 bars
Step-by-step explanation:
Total no. of gold bars = 24.
Fraction of bar captain allocated to himself = 1/3 of the bars
no. of bars he allocated to himself = 1/3 of 24 = 1/3 * 24 = 8
Fraction of bar captain allocated to his friend bill = 1/4 of the bars
no. of bars he allocated to his friend bill = 1/4 of 24 = 1/4 * 24 = 6
No . of bars captain allocated to rest of crew = 7
Total no of bars which are allocated altogether =
no. of bars he allocated to himself +no. of bars he allocated to his friend bill +No . of bars captain allocated to rest of crew
substituting the value of above summation variable as calculated above we have
Total no of bars which are allocated altogether = 8+6+7 = 21
No. of bars left = total no. of bars - Total no of bars which are allocated altogether = 24 - 21 = 3
Thus 3 gold bars are left.
Answer:
38.2842 m
Step-by-step explanation:
The acceleration is given by ...
a = ∆v/∆t
and the distance traveled is given by ...
d = 1/2at^2
So the distance we're looking for is ...
d = (1/2)(21.0366 m/s)/(8.06 s)(5.41632 s)^2 = 32.2842 m
