For this question you can say:
log(x-2) - log(x+1) = -1
and you should know that log(x-2) minus log(x+1) is equal to:
log((x-2)/(x+1))
so now you have:
log((x-2)/(x+1)) = -1
now you can say:
(x-2)/(x+1) = 10^ -1 or (x-2)/(x+1) = 1/10
now you can say:
10(x-2) = x+1
10x -20 = x +1
10x - x = 20+1
9x = 21
x = 21/9
x = 7/3 :)))
I hope this is helpful
have a nice day
Answer:
6.7
Step-by-step explanation:
Since the ratio of sides is 4 to 3, the proportion is:
x =
