<h2>
Answer:</h2>
The different possible routes are :
181440
<h2>
Step-by-step explanation:</h2>
We are asked to find the number of different routes that are possible to choose 7 locations among the 9 locations remaining.
This means that we have to chose the locations and also we have to arrange them in different orders according to the different order of locations.
The method we have to use is a method of permutation.
When we have to chose and arrange r items out of a total of n items then the formula is given by:

Here we have: n=9
and r=7
Hence, the different possible routes are:

Hence, the answer is:
181440
Answer:
(5+7x)^2
Step-by-step explanation:
25+70x+49x^2
This is a perfect square trinomial
a^2 +2ab + b^2 = (a+b)^2
5^2 *2*5*7x+ (7x)^2 = (5+7x)^2
$6469.177
I could be wrong but I'm pretty sure that is right.
75% cus u divide the denominator by the numerator is 5 and 8
Answer:
$1.25
Step-by-step explanation:
This can best be determined using a set of linear equations that are solved simultaneously.
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations.
Let the cost of a cookie be c, cost of a doughnut be d and that of a box of doughnut hole be h then if cost of 4 cookies, 6 doughnuts, and 3 boxes of doughnut holes is $8.15, we have
4a + 6d + 3h = 8.15
and the cost of 2 cookies, 3 doughnuts, and 4 boxes of doughnuts holes is $7.20 then
2a + 3d + 4h = 7.20
Dividing the first by 2
2a + 3d + 1.5h = 4.075
subtracting from the second equation
2.5h = 3.125
h = 1.25
The cost of a box of doughnut holes is $1.25
