Answer:
125 cookies
Step-by-step explanation:
13 x 9= 117. Add 8 to the total cookies and now she has 125 cookies in total!
6x-1=4x+6
Subtract 4x from each side
2x-1=6
Add 1 to each side
2x=7
Divide by 2 to isolate the variable
6(7/2)-1=21-1=19cm
I hope this is helpful.
Answer:
~8.66cm
Step-by-step explanation:
The length of a diagonal of a rectangular of sides a and b is

in a cube, we can start by computing the diagonal of a rectangular side/wall containing A and then the diagonal of the rectangle formed by that diagonal and the edge leading to A. If the cube has sides a, b and c, we infer that the length is:

Using this reasoning, we can prove that in a n-dimensional space, the length of the longest diagonal of a hypercube of edge lengths
is

So the solution here is

T - ( - 10) = 9
t + 10 = 9
t = 9 - 10
t = -1

Answer: t = -1

Answer:
the answer would be 81
Step-by-step explanation:
6 to the second power would be 36 then you would multiply 36x2 and it would equal 72. then you would do 2x6 which is 12. then 72+12-3= 81
