I think I might have my math wrong here but I think 5
The probability of getting a green marble here is 7/10
Answer:
Step-by-step explanation:
multiply the one to each bracket =
(x +2)+ (x-1) = 3 add the Xs and the numbers
x+X = 2x
2+(-1)= 1
2x+1=3
2x=3-1
2x =2
x =2/2
x =1

Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points
and
is
So the midpoint of your segment is
Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.
