We also need inflatable floats. If you inflate all the floats by yourself, it will take you about 2 hours. If your
classmate help, it takes both of you 1.2 hours to inflate
all the floats. How long does it take your classmate do
the work alone? (Please explain and show your work if you know the answer)

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
