Answer:
r≈5.36656314
Step-by-step explanation:
Since A=πr(r+
) so we get that 226.08/pi≈72 or 226.08/3.14=72 we then plug it in to get 72=r(r+
) so we get r≈5.36656314

Let the balance = Y and the number of weeks = x
She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.
You would then want to subtract that from the amount she started with in her account.
The equation becomes: Y = 150 - 15x
Answer:
x = -34.8
Step-by-step explanation:
<h2><u>solve the equation</u></h2>
2(x-3)
= 2x - 6
7(x + 24 )
= 7x + 168
put the equation together
2x - 6 = 7x + 168
now make x subject of formula:
2x - 7x = 168 +6
-5x = 174
x = 174/ -5
<h3><u>x = -34.8 </u></h3>
