I believe there are 20 quarters and 3 nickels.....

Total value of the jar is $5.15.....

Quarters are worth 25 cents
And nickels are worth 5 cents.

First you know that there are 4 quarters in a dollar.
You have 5 dollars so you do 4 x 5 = 20

So five dollars ($5.00) is 20 quarters.
And you still have 15 cents left.

Because quarters are 25 cents the rest are nickels.

Nickels are worth 5 cents so you'd do 5 x 3 = 15.

15 cents!

Add all this together and get $5.15.

So your answer is

There are 20 quarters and 3 nickels in the jar.

3. Write an equation for the line perpendicular to y = 6x - 5 that contains (2, 10)

Artemon [7]

<u>Answer:</u>

$y = -\frac{1}{6}x +\frac{31}{3}$

<u>Step-by-step explanation:</u>

We are to find the equation for the line which is perpendicular to another line with the equation $y = 6x - 5$ and passes through a point (2, 10).

Since the slope of a line which is perpendicular to another line is the negative reciprocal of the other line, therefore the slope of our line will be $-\frac{1}{6}$ .

Finding the y-intercept:

$y=mx+c$

$10=-\frac{1}{6} (2)+c$

$c=\frac{31}{3}$

Therefore, the equation of the line will be $y = -\frac{1}{6}x +\frac{31}{3}$ .
