Answer:
$13.
Step-by-step explanation:
Let x represent money that Alison has.
We have been given that Leo has 7 times as much money as Alison had. So the amount of money that Leo has, would be 
.
We are also told that Leo had $91, so we will equate with 91 and solve for x as:
To solve for x, we will divide both sides by 7:
Therefore, Alison has $13.
A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum:
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs
15^2=9^2+B^2
225=81+B^2
225-81=B^2
144=B^2 (square root both sides)
12=B

The number which when substituted in a polynomial makes its value zero.
zero , or a root of the polynomial
If it the one that says which double fact should you use for
6+5
it would be 5+5
which is 10 and then you could add the 1
Astronomers deal with objects in space, so it's most likely they would use geometry to determine how far they are, how big they are, etc.
Have a nice day! :)
