If Lianne has some dimes and nickels with a total value of $4.60. The number of dimes she has is 4 more than 3 times the number of nickels then 0.15 Nickels does Lianne has.
<h3>What is Equation?</h3>
Two or more expressions with an Equal sign is called as Equation.
Given,
Lianne has some dimes and nickels with a total value of $4.60.
The number of dimes she has is 4 more than 3 times the number of nickels.
We need to find number of nickels
From the given information
N+D=4.60
D=3N+4
N+3N+4=4.60
4N=4.60-4
4N=0.6
Divide both sides by 4
N=0.15
Hence, 0.15 Nickels does Lianne has.

Answer:
(an -a1)/d +1 = n
Step-by-step explanation:
Undo what is done to n, in reverse order. When evaluating this expression, you ...
- subtract 1 from n
- multiply the difference by d
- add a1
When you undo these, you get ...
... an -a1 = d(n-1) . . . . . . subtract a1
... (an -a1)/d = n - 1 . . . . divide by d
... (an -a1)/d +1 = n . . . . add 1
