Sum of interior angles = (n-2) × 180<span> = (5-2) x 180 = 3 x 180 = 540
so
x + 90 + 107 + 144 + 138 = 540
x + 479 = 540
x = 540 - 479
x = 61</span>
E=number of eight cent stamps
t=number of ten cent stamps bought
w=number of 2 cent stamps bought
number of eight=number of ten
e=t
as many 2 cent as the other 2 combined
e+t=w or
2e=w=2t
total she bouthgt 4.40
4.40=440 cents
8e+10t+2w=440
solve for t or e, I solve for t
8t+10t+2(2t)=440
18t+4t=440
22t=440
divide 22
t=20
t=e
20=e
w=2e
w=2(20)
w=40
answer is
20 eight cent
20 ten cent
40 two cent
P = 41,000(1.05)^5
P = 41,000(1.27628)
P = 52,327
