Answer:
15 dimes and 14 quarters.
Step-by-step explanation:
Let q represent number of quarters and d represent number of dimes.
We have been given that a collection of dimes and quarters contains 29 coins. We can represent this information in an equation as:
We know each dime is worth $0.10 and each quarter is worth $0.25.
We are also told that the total value of coins is $5. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, there are 15 dimes in the collection.
Upon substituting in equation (1), we will get:
Therefore, there are 14 quarters in the collection.
Answer:
15x - 12
Step-by-step explanation:
3(5x-4)
We can find an equivalent expression by distributing the 3 to what's inside of the parenthesis (5x and -4)
3(5x-4)
* Distribute *
3 * 5x = 15x
3 * -4 = -12
An equivalent expression would be 15x -12
