The problem statement gives a relation between the amount removed from one bag and the amount removed from the other. It asks for the amount remaining in each bag. Thus, there are several choices for variables in this problem, some choices resulting in more complicated equations than others.
Let's do it this way: let x represent the amount remaining in bag 1. Then the amount removed from bag 1 is (100-x). The amount remaining in bag 2 is 2x, so the amount removed from that bag is (100-2x). The problem statement tells us the relationship between amounts removed:
... (100 -x) = 3(100 -2x)
... 100 -x -3(100 -2x) = 0 . . . . . . subtract the right side
... 5x -200 = 0 . . . . . . . . . . . . . . eliminate parentheses and collect terms
... x -40 = 0 . . . . . . . . . . . . . . . . .divide by 5
... x = 40 . . . . . . . . . . . . . . . . . . . add 40
- 40 kg is left in the first bag
- 80 kg is left in the second bag

The amount removed from the first bag is 60 kg. The amount removed from the second is 20 kg. The amount removed from the first bag is 3 times the amount removed from the second bag, as described.
Answer:
Step-by-step explanation:
Pythagoras theorem states that <em>“In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides”</em>.
So,
Length of leg y of the right triangle = 13
The answer is A and B
Because if you look closely it says trucks to SUV's
It says truck first so the trucks would be 7 and the SUV's would be 2
Answer:
I think the answers C
Step-by-step explanation:
because the numbers match up to the equation and the symbols
The y-intercept is the flat fee and the slope is the per-person cost.
