Answer: x = 995
Step-by-step explanation:
In this equation our log doesn't have a base so it is given the default base of 10. This makes our equation really.

Now we put every equation as the exponent of our base 10 looks like this:

Now we cancel out the log base 10 and the 10. We are left with:
(x+3) + (2) = 10^3
Lastly solve for x
x + 5 = 1000
x = 995
Step-by-step explanation:
Use properties of similar triangles.

3 1/9 = 3 4/36
2 1/4 = 2 9/36
3 4/36 + 2 9/36 = 5 13/36
