Answer:
problem given: (-0.75x + 6) -(2.5x -1.9)
distribute: -0.75x+6 -2.5x-1.9
combine like terms: -0.75x-2.5x= -3.25x ; 1.9+6=7.6
solution: -3.25x+7.6
I would say A because every other question it shows the exact amount but since it says 20-29 you can’t really say the answer by looking at the graph unless you guess but that’s not what the question is saying it’s saying which question cannot be answered by looking at the graph and I would Say You cannot answer A by looking at the graph.
Sorry if I am wrong
You would start by finding the total amount of marbles, which in this case is 20.
Then find the total amount of blue AND green balls. 10.
Then put 10/20, simplify, and you have yourself 1/2.
