Circumference is: C = 2<span>πr
</span>Circumference of the bigger circle (outer tire) is 157ft. Circumference of the smaller circle (inner tire) is 132ft.
<span>50π - 42π, which is 8</span>π
the answer is 4 be cause 36 / 4 = 9
for 3 hours, both studios charge the same amount.
<h3>
After how many hours are the total costs the same at both studios?</h3>
The cost equation for studio A is:
A(x) = 10.49 + 8*x
The cost equation for studio B is:
A(x) = 14.99 + 6.5*x
The cost will be the same when A(x) = B(x), then we just need to solve the linear equation:
10.49 + 8*x = 14.99 + 6.5*x
8x - 6.5x = 14.99 - 10.49
x = (14.99 - 10.49)/(8 - 6.5) = 3
This means that for 3 hours, both studios charge the same amount.

It’s very confusing so I lost track right now I think it’s A
Answer:
1. x = -1 or x = -3
2. x = 1 or x = -3
3. x = 3 or x = -7
4. x = 1/2 or x = -2
5. x = -2/3 or x = 4
Step-by-step explanation:
I'm guessing these are what you needed, you didn't specify.
