He put 12 stamps in his collection.
Karen = x
bill = 2x - 9
total = x + 2x - 9 = 3x - 9
Answer:
you have to add together all the numbers you where given then divide
Step-by-step explanation:
calculate length of the sides of the rectangle and multiply then do the same with the parallelogram
Total area is 51 square units
So we are trying to get the “y” alone, so to undo the division by -8, we will multiply both sides by -8, then simplify.
(-8) y/(-8) = (-8) 1/16
y = -8/16
and simplified:
y = -1/2
