Circumference = (pi)(diameter)
As the deameter is 8, the answer is C. <span>8π m</span>
You need to split it into two problems so it becomes
-(3-2x/3)>5 and 3-2x/3>5
then you solve and the check for extraneous solutions by plugging in both answers into the origional equation.
23x-85=191 is the correct answer
This is a proportion and we have to solve for n.
Cross multiply:
36 × 100 = 3600
Divide:-
3600 ÷ 50 = 72
n = 72<span />
