Answer:
23
Step-by-step explanation:
It is given that, in Russia there are 21 rocket launch failures out of 743 total launches. We need to find no of failures for the next 800 launches.
21 rocket = 743 launches
1 launch = 
For 800 launches,

or
= 23 failures
So, there are 23 failures in next 800 launches.
Subtract z from the right side so that it becomes... u - z = vw
Then all you do is divide the right side of the equation(or equals sign) by w because your goal is to get whatever you're solving for by itself.
Your answer, then, is... u-z/w = v
