5 times 12 = 60

Step-by-step explanation:

5 times 12 is at least 60

x = 16

y = 14

Step-by-step explanation:

The figure is a parallelagram.

That means that the diagonals bisect each other.

x = y + 2                  Subtract 2 from both sides

x - 2 = y                   Switch

y = x - 2

y + 10 = 2x - 8         Subtract 10 from both sides

y = 2x - 8  - 10

y = 2x - 18

Now the ys have to be equal so equate the right side of each equation.

2x - 18 = x - 2          Add 18 to both sides

2x = x - 2 + 18

2x = x + 16               Subtract x from both sides

2x - x = 16

x = 16

y = x - 2

y = 16 - 2

y = 14
