Bridget is on her middle school's basketball team In its last game her team made 31 of its shots. Some of those were free throws, worth 1 point each, and some of those were regular field goals, worth 2 points each. The team didn't make any 3-pointers and finished the game with 49 points. This system of equations can be used to represent the situation: x+y=31 x+2y=49 Which statement is correct? In the system of equations, x represents the number of points scored from free throws, and y represents the number of points scored from field goals. In the system of equations, x represents the number of field goals made, and y represents the number of free throws made.

To solve this problem, we need to determine the values of x and y in the system of equations.<br /><br />Given information:<br />- The team made 31 shots in total.<br />- The team scored 49 points in total.<br />- The system of equations is:<br /> x + y = 31<br /> x + 2y = 49<br /><br />Step 1: Solve the system of equations.<br />Subtract the first equation from the second equation to eliminate x:<br />x + 2y - (x + y) = 49 - 31<br />y = 18<br /><br />Substitute y = 18 into the first equation to find x:<br />x + 18 = 31<br />x = 13<br /><br />Therefore, the correct statement is:<br />In the system of equations, x represents the number of free throws made, and y represents the number of field goals made.<br /><br />Step 2: Calculate the number of points scored from field goals.<br />Since y = 18, the number of field goals made is 18.<br /><br />To find the number of points scored from field goals, we need to multiply the number of field goals (y) by the points per field goal (2 points):<br />Points scored from field goals = 18 × 2 = 36<br /><br />Therefore, Bridget's team scored 36 points from field goals.
