There are 3 choices for the pants. Having selected a pair of pants there are 2 choices for a shirt. Therefore there are 3 * 2 possible choices for a pair of pants and a shirt. Each of these 6 possible choices can be combined with each of the 3 possible choices of a pair of shoes. So, the total number of choices of outfit is given by:

Answer:
It just means "5-n"
Step-by-step explanation:
There's really nothing to it. It's just an expression, it doesn't 'mean' anything.
<span>We can represent the number of pies she makes to be x.
We also need to add $30 to the equation to take the baking supply cost into consideration.
The Cost can be represented by C.
C = 5x + 30 is the equation to use to determine the Cost! 5 times the number of pies she makes plus the $30 for baking supplies!
If we look at just the cost when she doesn't sell any pies, we can say x = 0
That means C = 5(0) + 30 or C = 30, it means that she has to pay $30 or the Cost is $30 when she sells no pies.
This makes sense since the baking supplies were $30.
Are you with me so far?</span>
Let x be the digit in the tens place and y be the digit in the ones place.
so, the digit is xy
<span>
The ten's digit of a two digit number is 1 more than 4 times the units' digit.
</span>x = 4y + 1
<span>63 is subtracted from the number, the order of the digits is reversed
</span>10x + y - 63 = 10y + x
9x - 9y = 63
x = 4y + 1 ------------ (1)
9x - 9y = 63 ---------- (2)
Sub (1) into (2)
9(4y + 1) - 9y = 63
36y + 9 - 9y = 63
27y = 63 - 9
27y = 54
y = 2 ------- sub into (1)
x = 4(2) + 1 = 9
x = 9, y = 2
The number is 92
