Answer: 1/(x+2)Step-by-step explanation:=(x-2)(1)/(x-2)(x+2) cancel (x-2)=1/(x+2)
Step-by-step explanation:
You have to use the formula for simple interest.
(Investment) * (1 + (intrest rate))^(number of periods)
So:
200 * (1 + 0.05)^7 = 281.42 $
So we can take X as the n.o of pages of the entire book
so 1x/5 +40= 7x/10
pls remember the total n.o of each book is X
therefore
40=7x/10-1x/5
to solve this u need to make the denominator's the same
40=7x/10-2x/10
40=5x/10
40*10=5x
400=5x
400/5=X
80=x
