Answer:

x = -24

Step-by-step explanation:

3(x + 7) = 2x - 3

3 * x = 3x

3 * 7 = 21

3x + 21 = 2x - 3

-21            -21

3x = 2x -24

-2x   -2x

x = -24

A is 6:55

B is 37 Minutes

C is 15:12

Step-by-step explanation:

so basically its just adding minutes to a clock, like if its 1:00 o clock and 40 minutes pass it will be 1:40 or if its 12:00 and 25 minutes pass it will be 12:55. There's 60 minutes in an hour so if the time is, let's say, 12:45 and 30 minutes go by itd be 1:15.

C is a little more tricky but thats just because its military time.:) basically instead of going to 12 am to 1 pm it would go from 12:00 AM to 13:00 PM

This is because there is one day where only 2 books were checked out while on all of the other days 35-45 books were checked out.

2.) 0; it represents no correlation between x and y

This is because no matter the age they could answer 17 questions

Hope this helps!

HELP RIGHT NOW PLEASE!!!!!!!!!!!! What is the value of x?
barxatty [35]

Answer:

x = 34

Step-by-step explanation:

Add together all three angles because together they equal 180 degrees

x + 12 + x + 100 = 180         Combine like terms

2x + 112 = 180

     - 112   - 112                   Subtract 112 from both sides

2x = 68                              Divide both sides by 2

x = 34
