Answer:
The number of nickels is 17 and number of dimes is 8.
Step-by-step explanation:
Let the number of nickels be x and number of dimes be y.
Total number of coins is 25.
.... (1)
.... (2)
On solving (1) and (2), we get
Put this value in equation 1.
Therefore the number of nickels is 17 and number of dimes is 8.
Rob has 15 nickels and 10 dimes. This conclusion is reached via a system of equations, considering both the number of coins and the total worth in cents.
This problem can be solved using a system of equations. Let's denote the number of nickels as n and the number of dimes as d. We have two equations here:
From equation [1], we can express d in terms of n (d = 25 - n) and substitute it into equation [2] to find the value of n.
Doing this, we find that n = 15, which means d = 10. So, Rob has 15 nickels and 10 dimes.

The area of figure ABCD is:
24 square units.
We see that the given points form the vertices of a trapezium ABCD with bases AD and CB with measure,
AD= 3 units
and CB=5 units
and the height of the trapezium is: AB= 6 units.
Hence, the area of trapezium ABCD is:
Hence, the area of figure ABCD is:
24 square units.
