A collection of nickels and quarters has a total value of three dollars and contains 32 coins. Which of the following systems of equations could be used to find the number of each coin?

and

Step-by-step explanation:

Given that there is a collection of nickels and quarters.

Let N be the number of coins of nickels and

Q be the number of coins of quarters.

It is given that total number of coins are 32.

Number of coins of nickels + Number of coins of quarters = 32

is the first equation.

Now, we know that value of a one quarter coin is 25 cents or

and value of a one nickel coin = 5 cents = $0.05

Total value of all nickel coins = Number of nickel coins value of one nickel coin =

Similarly,

Total value of all quarter coins = Number of quarter coins value of one quarter coin =

Total value of coins is 3 dollars.

is the second equation.

So, the answer is:

and

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

80 the answer is 80
