The median is the middle score, it is also the average of the two middle scores when total number is even.
original 3 scores: 89, 90, 95 ----> median = 90
with final score: 89,90,X,95 ----> median = 91.5
(90+x)/2 = 91.5
90+x = 183
x = 93
Final score was a 93.
(2,1) is the solution because its where they both intersect..
5x means that 5 should be multiplied by the value of x
Every time a variable is touching a number it means it’s multiplying
5x + 8 = ?
If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8
45 + 8 = 53
Therefore 5x + 8 = 53
Hope this helps you! :)
