At the beginning of the week, Paloma opened a new box of 275 coffee creamers. Sixty-four coffee creamers were used during the week. Which equation could be used to find x, the number of coffee creamers left at the end of the week? A. 64x = 275
B. x - 64 = 275
C. 64 - 275 = x
D. x + 64 = 275

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.
