Answer:

$5.24

Step-by-step explanation:

First, we need to find how many of each coin type we have. For pennies and dimes, we can take the percentage and divide by two for the number of coins.

18 / 2 = 9 pennies

36 / 2 = 18 dimes

We also know that there are three more nickels than there are dimes.

9 + 3 = 12 nickels

We can subtract the total number of nickels, pennies, and dimes from the total number of coins to get the number of quarters.

50 - 39 = 11 quarters

Then, we do the math to find the value.

9 x 0.01 = 0.09

18 x 0.10 = 1.80

12 x 0.05 = 0.60

11 x 0.25 = 2.75

2.75 + 1.80 + 0.60 + 0.09 = $5.24

What's y=3x-3 2y-x=4 as an ordered pair

matrenka [14]

I don’t wanna give the exact answer, i want to help you and lead you in the right place so you know the concept and process if a similar question is on an assessment. basically, the set of equations is set up for substitution method. we can agree that y equals 3x-3. so in the second equation, instead of writing “2y” you would SUBSTITUTE the y for 3x-3. so the equation would be 2(3x-3)-x=4. do the distributive property. once you get the equation after doing the distributive property, you solve for x using your algebra skills from previous units (cancel out x’s, for instance). your answer is your x coordinate. in order to find your y, you substitute whatever number you got for x and plug it in to one of the equations, doesn’t matter which. you will then solve for Y using your algebra skills you learned from previous units. after solving, you should get what y=. now you put the number in coordinate pair form which is (x,y)

The square root of 5 is between which two integers? Explain your reasoning.

tankabanditka [31]

The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property

The mayor gets elected every four years. Treasurer gets elected every six years. Both were elected this year. How many years bef

aleksandrvk [35]

<h3>There are 11 years before both the elections happen in the same year.</h3>

Step-by-step explanation:

The mayor gets selected once in every 4 years.

So, the number of years the mayor elections takes place

= 1, 4 ,8, 12, 16, 20, 24, 28,....

Now, the Treasurer gets selected once in every 6 years.

So, the number of years the Treasurer elections takes place

= 1, 6, 12, 18, 24, 30

Now,as we can see from both statements, the year in which both elections happen are the common factors of 4 and 6.

The first common factor of 4 and 6 is 12.

So,in twelfth year both elections happen in the same year again.

Hence, there are 11 years before the elections happen in the same year.
