Patty has 44 coins, all nickels, dimes and quarters, worth a total of $6.45. She has 3 times as many dimes as nickels. Set up an

kherson [118]

Answer: There are 7 nickles, 21 dimes and 16 quarters.

Step-by-step explanation:

Since we have given that

Number of coins = 44

Let the number of nickels be 'x'.

Let the number of dimes be '3x'.

Let the number of quarters be

$44-(x+3x)\\\\=44-4x$

According to question, we get

$0.05x+0.10(3x)+0.25(44-4x)=6.45\\\\0.05x+0.3x+11-x=6.45\\\\-0.65x=6.45-11\\\\-0.65x=-4.55\\\\x=\dfrac{4.55}{0.65}\\\\x=7$

So, there are 7 nickles,

3x = $3\times 7=21$

$44-4x=44-4\times 7=44-28=16$

Hence, there are 7 nickles, 21 dimes and 16 quarters.

What is the equation of a circle with Center -3, -5 and radius 4

Rus_ich [418]

The formula is (x-h)^2+(y-k)^2=r^2
so, using this, and knowing that h is -3 and k is -5 and r is 4, we get

(x--3)^2+(y--5)^2=(4)^2, which equals
(X+3)^2+(y+5)^2=16
