Answer:
11. Not enough information
12. You can say DB = DC by SAA congruence rule and CPCTC (Corresponding parts of congruent triangles are congruent)
Step-by-step explanation:
For 12, you can say ΔABD≅ΔACD because they have a side in common (AD) and they have 2 congruent angles. Thus, you can use the SAA congruence criterion. Then, you can use CPCTC (Corresponding parts of congruent triangles are congruent) to say that DB = DC.
Hope this helps :)
Closer to 2. If you round it, because the number after the 2 is less than 5 you round it down so it's closer to 2
Answer:
It takes Michael 1 hour, 14 minutes and 7 seconds to seal the driveway close

So it takes Michael 
to complete the work, or 
Answer:
x = 8
Step-by-step explanation:
10x - 2 (x + 6) = 52
Let X become 8
10 (8) - 2 (8 + 6) = 52
80 - 2 (14) = 52
80 - 28 = 52
52=52
5n-4 = 6 gives the equation for 5 times #Nathan rode less 4 miles which solves to n = 2
Nathan rode 2 miles. (5*2)-4 = 6 10-4=6 so 2 miles is right
