Gabe goes to the mall. If n is the number of items he bought, the expression 16.72n + 30 gives the amount he spent in dollars at one store. Then he spent 20 dollars at another
store. Find the expression which represents the amount Gabe spent at the mall. Then estimate
how much Gabe spent if he bought 5 items.
What expression represents the amount in dollars that Gabe spent at the mall?

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.
