Can some one me with this problem here?

You are on the right track in terms of the expressions you created.

Ronnie: x Lisa: 2x+500+650 Mark:2x+500

To solve for how much everyone contributed, we have to solve for x, then use the rest of the expressions to solve for each person. Since we know the TV cost $2000, we can add all the expressions together and solve.

2000=x+2x+500+650+2x+500

2000=5x+1650

5x=2000-1650

5x=350

x=70

Now that we know x=70, we can use our expressions to solve for what each person contributed. Ronnie is easy because we already know he contributed $70.

Lisa: 2x+500+650 L:2(70)+1150 L:140+1150 Lisa: $1290

Mark: 2x+500 M:2(70)+500 M:140+500 Mark: $640

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
