Your answer would be -17 I think
If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x
5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25
5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.
1 ton = 2000 pounds
0.05 ton = x
1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.

Answer:
C
Step-by-step explanation:
You need to isolate the y variable. The first thing you need to do is move the 2 and 3x to the other side of the equation.
3x + 1/5y - 2 = 0
1/5y = -3x +2
Then you need to get rid of the 1/5 so you multiply both sides equation by the reciprocal of 1/5 which is 5/1 or 5.
y = ( -3x +2) 5
then you distribute the 5 to get
y = -15x+10
