4 parts = 4 × 7 = 28 ← number of short boards
The median is 50, answer B. It is the middle number of the data set so it is the median. If there are an even set of numbers, so obviously there will be two numbers in the middle, then you simply need to add them and divide by two. Hope this helps! :)
Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
