Answer:
The answer is c and we'll use c to get the actual answers.
A) n + q = 104
B) .05n + .25q = 22 we'll multiply B) by -4
B) -.2n -1q = -88 then we add A)
A) n + q = 104 which equals
.8n = 16
n = 20 nickels
q = 84 quarters
20 nickels = $1
84 quarters = $21

Answer:
11
Step-by-step explanation:
180 - 112 = 68
4x + 16 +5x - 3 + 68 = 180
simplify.
9x + 81 = 180. subtract 81 from 180
9x = 99. divide 99 by 9
x = 11.
Answer: D.) 32/5
Step-by-step explanation:
As this geometric series is an infinte series , The Sum of this series can be determined with the help of the formula written below.

a = First term of the geometric series = 8
r = The common ratio between the terms =
Now,
By substituting the values in the above formula we get,
=
