Step-by-step explanation:
We have given that,
The inner radius of a bicycle wheel is 12 inches.
It is required to find the expression to find the inside circumference of this wheel.
The outer surface of the wheel is equal to its circumference. It is given by :

r is radius of wheel

This is the required explanation.
2y = x-6, x=9
2y = 9-6; plug 9 in for x
2y = 3; evaluate 9-6
y = 3/2; divide each side by 2
x = 9
y = 3/2
Hope this helps!
Answer:
3^13*73
Step-by-step explanation:
3^17-3^15+3^13 So you factor out 3^13
=3^13(3^4-3^2+1)
3^4-3^2+1=73
3^13*73
Is this RSM?
Answer:
x=12.8
Step-by-step explanation:
xy / 8 = 16 /10
xy = (8 * 16) / 10
xy = 12.8
Answer:

Step-by-step explanation:
<u>Algebra Simplifying</u>
We are given the expression:

We need to repeatedly use the following identity:

For example, the first numerator has a difference of squares thus we factor as:

The first denominator can be factored also:

Applying the same procedure to all the expressions:

Simplifying all the fractions:

Since all the denominators are equal:

Simplifying:

Simplifying again:
T = 1
Thus:
