41 coins, consisting of nickels and quarters, have a total value of $4.65. how many coins of each kind are there?

You first have to make an simple equation.

= How many pennies

= How many quarters

After that, since a penny is 5 Cents and a quarter is 25 Cents, we make the equation as:

(cents)

To write the whole entire thing in an equation is:

   Since I brought the x from the left to right, we change the positive "" to negative ""

To bring the '' to , we get rid of the ""s from both equations.

Now, you are left with the simplified equation:

Now you find the .

= 28

Conclude:

So the y was the quarter and the x was the pennies.

Quarters = 13

Pennies = 28

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
