Answer:
x = 20
Step-by-step explanation:
Since ΔACB ≅ ΔDCE then ∠A ≅ ∠D, that is
3x - 10 = 2x + 10 ( subtract 2x from both sides )
x - 10 = 10 ( add 10 to both sides )
x = 20
Step-by-step explanation:
We have,
First terms of geometric sequence, a = 0.3
Common ratio, r = 3
It is required to find the 12th term of a GP. The formula of the nth term is given by :

Here, n =12
So,

or

So, the 12th term of the GP is 53144.
Division and addition are the only operations involved.
So the question is asking to write a multiplication problem that uses two decimals that has a product greater than 0.1 but less than 0.2 and in my further computation, I would give an example of 0.5*1.5 equals 0.75. I hope you are satisfied with my answer and feel free to ask for more
