If the original volumes of liquid is represented by x, we have x=x for A and B. Since 120mL is poured from A to B, A loses 120 mL (x-120) and B gains 120 mL (x+120). Since we know that B contains 4 times as much liquid as A is now (x-120), we have 4*(x-120)=(x+120)=B. Using the distributive property, we get 4x-480=x+120. Adding 480 to both sides, we get 4x=x+600. After that, we can subtract both sides by x to get 3x=600. Lastly, we can divide both sides by 3 to get x=200=the original amount of liquid. Since A=x-120, we get A=200-120=80
Multiplying a number by -1 makes the number a negative version of itself. For example, if you were to multiply 3 by -1, you would end up getting a product of -3.
Answer:
I think the answer is 3
Step-by-step explanation:
I know the 24 can go into 12 twice, and I know 3 can go into 9 three times. Don't know if this is the real way to solve it, but I do think this answer is correct. If not I am truly sorry. Let me know either way. :) Thanks!
The answer is A because u can subtract the 3x to get 2y by itself then divide by 2 to completely get y by itself and it would be y=-3/2x - 9/2
