Y = mx + b.....subtract mx from both sides
y - mx = b
Since one piece is four time the length <em>x, </em>we can represent that as 4x.
Thus making the equation:
4x+x=275
5x=275
x=55
4(55)=220
220+55=275
So, the length of the longer piece is 220 inches, and the length of the shorter piece is 55 inches.

Steps on finding the volume of water :
1. volume . pour enough water from your cup into the graduated cylinder.
2. density . calculate the density by using the formula D=M/V . record the density in (g/m ) ^3 .
3. identify the samples . compare the values for density you calculated to the values in a chart.
Answer:
Solving equation i and ii, we get;
3x-3y+x+3y=9+12
4x=21
x=21/4
Putting the value of x in equation ii.
(21/4)+3y=12
3y=12-(21/4)
3y=(48-21/4)
y=27/(4*3)
y=9/4
