-65=6b-11<br><br> hi I don't understand how to solve this equation<br> can someone please explain :)

belka [17]

-65=6b-11

Add 11 to both sides to get rid of the -11 on the right side

-54=6b

Then divide both sides by six to find the value of b

-9=b

So b is -9

Find the number of permutations of the first 10 letters of the alphabet, taking 3 letters at a time.

allsm [11]

Answer:

720

Step-by-step explanation:

The permutation looks like this for that set of data:

$_{10}P_{3}$

and the formula to solve it like this:

$_{10}P_{3} =\frac{10!}{(10-3)!}$

which simplifies down to

$_{10}P_{3} =\frac{10!}{7!}$

Since every number less than 8 in the numerator cancels out with the denominator, we have

$_{10}P_{3}=10*9*8$

which equals 720
