Answer:
what should we do ,...?
Step-by-step explanation:
please write your questions!
Volume = length x width x height
So,
Volume = 2 1/3in x 2in x 1 2/3in
Volume = 7/3in x 6/3in x 5/3in
Volume = 210/9in^3
Volume = 70/3in^3 or 23 1/3in^3
Answer: D. n + q = 20
5n + 25q = 300
Step-by-step explanation:
Let n represent the number of nickels that you have.
Let q represent the number of quarters that you have.
Suppose you have 20 coins. It means that
n + q = 20
The total value of the coins is $3. The value of a quarter is $0.25 and the value if a nickel is $0.05. Therefore, the equation would be
0.05n + 0.25q = 3
Multiplying both sides of the equation by 100, it becomes
5n + 25q = 300
The correct option is
D. n + q = 20
5n + 25q = 300
