Let
n-------> the number of nickels
d-------> the number of dimes
we know that
so
-----> equation A
-------> equation B
substitute equation B in equation A
------> equation that can be used to find n
Solve for n
find the value of d
therefore
the answer is
The equation that can be used to find n is
The number of nickels in the collection is
Answer:
Danny offers better deal .
Step-by-step explanation:
As given
Danny charges $35 for 3 hours of swimming lessons.
Cost of one hour = $ 11.67 (Approx)
Martin charges $24 for 2 hours of swimming lessons.
Cost of one hour = $ 12
As the cost charge by Danny for one hour is less as cost charge by Martin .
Therefore Danny offers better deal .
Danny charges about 11.67 per hour
Martin charges about 12 per hour
So, Danny offers a better deal.

The sequence 5, 9, 14, 20 is not arithmetic.
Yes, the sequence 5, 9, 14, 20 is an arithmetic sequence.
To determine if a sequence is arithmetic, we need to check if the difference between consecutive terms is constant.
In this sequence, the difference between consecutive terms is:
9 - 5 = 4
14 - 9 = 5
20 - 14 = 6
Since the differences are not constant, the sequence is not arithmetic. The answer is no.

Answer: No
Step-by-step explanation:
An arithmetic sequence is one where the same number is being added to the number before it. For example, 2, 4, 6, 8..., where 2 is being added to each number.
In this case, however, the number being added is not consistent with this pattern. Between 5 and 9, the difference is 4 and between 9 and 14, the difference is 5, and so forth. This pattern does not follow the rules of an arithemtic sequence.
Answer:
Step-by-step explanation:
4 because as shown below. An equilateral triangle has 3 lines of symmetry.
Answer:
D
Step-by-step explanation:
The zeros are the values of x on the x- axis where the graph crosses.
The graph crosses the x- axis at x = - 4 and x = - 6
Then x = - 4 and x = - 6 are the 2 zeros → D
