Tommy wished he practiced more before his violin concert. If he had practiced 1 1/2 more hours one week, he would have averaged
Nimfa-mama [501]

Answer:

30.5 hours

Step-by-step explanation:

If he were to average 8 hours PER week for 4 weeks, his total sum would have been:

8 * 4 = 32 hours

But he fell short of it. By how much?

By 1\frac{1}{2} hours!

So, he practiced 1  1/2 hours LESS THAN 32 hours, so his practice time is:

32-1\frac{1}{2}\\=32-1.5\\=30.5\\=30\frac{1}{2}

So, <u>he practiced 30.5 hours in the 4 weeks</u>

HELPP WITH MATH PLEASSS 11-12
evablogger [386]

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 :)
