X = -12 - y + 2z / 5
I hope this helps. :)
We have to use basic combinatorics to solver his problem. We first have to determine what kind of problem this is.
Does order matter in this question? Yes it does. So it is a
permutation. Is is a permutation with repetition? No, because once a performer goes, they cannot perform again. Hence, we have defined this problem as a
permutation without repetition. The formula for this kind of question is:

Where n is the number of things we choose from, and p is the number of places we want to put them in.
There are 4 places for 4 performers, because 1st performer, lets call him
Joe, has already taken the 1st spot. Hence, we substitute our values:

=

=
There are 24 different ways to schedule this performance.
Hope this helped!

Answer:

Step-by-step explanation:


Convert the mixed number to an improper fraction

Invert the denominator and change division to multiplication

Cancel the 2s

Multiply numerators and denominators.

Convert the improper fraction to a mixed number.

It takes
stones to complete the path.
For the marble Question you are correct.
And the spinner for the prediction it would be 40.
Hope I helped you.
