Answer:
<u>There are 97 nickels in the jar</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of coins = 205
Number of nickels = x
Number of quarters = 205 - x
Value of the 205 coins = $ 31.85
2. If both of these statements are true, how many nickels are in the jar?
Let's solve for x, this way:
0.05x + 0.25 (205 - x) = 31.85
0.05x + 51.25 - 0.25x = 31.85
-0.2x = 31.85 - 51.25
-0.2x = - 19.4
x = -19.4/-0.2
x = 97 ⇒ 205 - x = 108
<u>There are 97 nickels and 108 quarters in the jar</u>
Answer:
he expression is undefined where the denominator equals
0
, the argument of an even indexed radical is less than
0
, or the argument of a logarithm is less than or equal to
0
.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
