5. If a = b, and b = c then a = c is the transitive property.

6. The converse is switching the order of the statement.

The answer would be If A <15, then a <10: true

7. You have RS + ST = RT

Using subtraction property  solve for RS by subtracting ST from both sides to get: RS = RT-ST

8. The addition property would be adding the same thing to both sides:

So. If p=q, then p+s = q+s

9. Vertical angles are the same:

6x-22 = 4x+2

Subtract 4x from both sides:

2x-22 = 2

Add 22 to both sides:

2x = 24

Divide both sides by 2:

x = 12
