One way is to find common factors
example
8/6=4/3 because 8/6, 8 and 6 have common factor of 2 so divide that out to get 4/3
basically divide the LCM from each
so factor
we can combine 36m-48m into -12m
we have
-12m/6m
common factor is 6m
-12m/6m=(-2)/1 times (6m)/(6m)=-2 times 1=-2
answer is -2
Answer:
The equation would be y = x + 5, in which x is the number of weeks and y is the number of books he has.
Step-by-step explanation:
We know this because even at 0 weeks, he still has 5 books. Therefore we put this as the constant at the end. Then we can add the number of weeks since the rate is one book per week.
Sin(2x)-sin(4x)=0
-2cos(3x)sin(x)=0
x=pi/6+2kpi/3
x=pi/2+2kpi/3, k=no solution
x=2kpi
x=pi+2kpi
Answer:
C
Step-by-step explanation:
You can think of the square root as 
which would multiply throughout producing the answer.
