Solutions to the equations: a. 5/2 * x = 1
Multiply both sides by 2/5: x = 2/5 b. x * 7/3 = 1
Multiply both sides by 3/7: x = 3/7 c. 1 / 11/2 = x
Multiply both sides by 11/2: x = 2
Drawing the scaled copy of the quadrilateral:
Identify the coordinates of the original quadrilateral ABCD. From the image, we can see that the coordinates are:
A: (2, 4)
B: (6, 4)
C: (6, 0)
D: (2, 0)
Multiply each coordinate by the scale factor 2/3. This will give you the coordinates of the corresponding points in the scaled copy A'B'C'D'.
A': (2 * 2/3, 4 * 2/3) = (4/3, 8/3)
B': (6 * 2/3, 4 * 2/3) = (4, 8/3)
C': (6 * 2/3, 0 * 2/3) = (4, 0)
D': (2 * 2/3, 0 * 2/3) = (4/3, 0)
Plot the points A', B', C', and D' on the grid. Connect the points with lines to form the scaled copy of quadrilateral ABCD.
