Answer:
144 ways
Step-by-step explanation:
Let's think of the 3 persons sitting together as "one". So essentially we have 3 + "1" = "4" persons to arrange.
THey can be arranged in 4! ways, which is:
4! = 4 * 3 * 2 * 1 = 24 ways
Now, the 3 persons themselves can be arranged in 3! ways, which is:
3! = 3 * 2 * 1 = 6 ways
Total ways = 4! * 3! = 24 * 6 = 144 ways
Answer:

Hello my name is Jeff (sorry)
The one you have highlighted is correct, that is the sign for congruent.
Answer:
v = 66/7
Step-by-step explanation:
Step 1: Write equation
-7v + 3 = -63
Step 2: Solve for <em>v</em>
<u>Subtract 3 on both sides:</u> -7v = -66
<u>Divide both sides by -7:</u> v = 66/7
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-7(66/7) + 3 = -63
-66 + 3 = -63
-63 = -63
