Divide all by 2
2/2n = 16/2
N=8
Answer:
n=8
Step-by-step explanation:
2/2n=16/2
1n=8
tax reduction: $20.34
amount you're paid minus tax: $657.66
(20+x)*2=x-6
40+2x=x-6
40=-x-6
46=-x
check:
x=-46
20-46*2=-46-6
-26*2=-52
-52=-52
A≈153.94cm²
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·142≈153.93804cm²
its the 3rd answer!
hope this helps
