2.8x10^-5 ; 2.8x10^-3 ; 2.8 ; 2.8x10^2 ; 2.8x10^4
The answer is 9/42. might be wrong I'm rusty on this.

Step 1: write the number as a product, helps visualizing common factors.

I've marked things being repeating, so, group them up

Now you have a common factor again

Extra, if you want to split the first one, you can see it as the difference of

and

which is further split into
The answer:
solve for x does mean, finding the value of x
as we see in the figure, the first step to find such a value is equalizing <span>3x-8 to
</span><span>2x+23, that is possible because the right angle was bisected by a line, so the value of each angle must be equal.
to find x, </span>3x-8 = 2x+23 , equivalent to 3x - 2x =23 +8 = 31
x =31°
finally
the steps are true, 1, 2 and 3
