Consider the first blank is the green box.
Given:
The equations are


To find:
The value belongs in the green box
Solution:
We have,
...(i)
...(ii)
Adding (i) and (ii), we get



So, the value for the first black is 2x. It means the value belongs in the green box is 2x.
The values of three blanks are 2x, 0 and 13 respectively.
Therefore, the correct option is B.
Since the distance in between each plate is 90ft. We know from home to 1st is 90ft. To get to 2nd from first is also 90ft. So 90 + 90 is 180ft.
Now this question is weird because it could be asking how far would a baseball player would have to run to get to 1st then 2nd
Or
Could be asking the distance from Home to 2nd without going to 1st. So just a straight line from home to 2nd.
If that’s the case we need to use the Pythagorean theorem
Our setup would be 90^2 + 90^2 = c^2
Adding A and B will get us 16200. Now we need to divide to get to the other side. But C is squared. So we need to Square root 16200. Which is 127.28ft.
