Find a common denominator to subtract, so smallest common denimator between 7 and 3 is 21
multiply 4/7 by 3/3 and 2/3 by 7/7
12/21-14/21= -2/21
I think it would be 2, 9 x 8
Acceleration is F/M = 250/30= 8.333m/s^2 downward

Answer:
The total number of albums sold on the first day=34
Step-by-step explanation:
Derive expressions for the number of albums sold
each day;
Let;
the total number of albums sold on the first day=x
the total number of albums sold on the second day=y
but,
total number of albums sold on the second day is twice the total number of albums sold on the first day, therefor=, y=2×x= 2 x
The total number of albums sold for the two days can be expressed as;
Total sales=number sold on the first day+number sold on second day
where;
Total sales=102
number sold on the first day=x
number sold on second day= 2 x
replacing;
(x+2 x)=102
3 x=102
x=102/3
x=34
The total number of albums sold on the first day=34
