Answer:

The age of three girls as

The age of Allison's is 8 years

The age of Kali is 48 years

The age of Lauren's is 24 years  

Step-by-step explanation:

Let The age of Allison's = A  years

The age of Lauren's = L  years

The age of Kali's = K years

Now, According to question

The sum of total ages of the three girl's = 80 years

I.e A + L + K = 80 years

And  ,

The age of Allison's = \frac{1}{3} of  The age of Lauren's

I.e A = \frac{1}{3} × L

And ,

The age of Kali's = 2 times The age of Lauren's

I.e K = 2 × L

∴ \frac{1}{3} × L + L + 2 × L = 80

Or,  \frac{1}{3}  L + 3 L = 80

Or, \frac{10}{3}  L = 80

So, 10 L = 3 × 80

∴   L = \frac{240}{10}

I.e L = 24  

The age of Lauren's = 24 years

Again ,

K = 2 × L

Or, k = 2 × 24

∴   k = 48

The age of Kali = 48 years

Similarly

A = \frac{1}{3} × L

Or, A =  \frac{1}{3} × 24

∴   A = 8 years

The age of Allison's = 8 years

Hence The age of three girls as

The age of Allison's is 8 years

The age of Kali is 48 years

The age of Lauren's is 24 years     Answer

What is the answer to the problem i need help with?
AveGali [126]

Answer:

C

Step-by-step explanation:

Recall the equation for a circle:

(x-h)^2+(y-k)^2=r^2, where the center is (h,k) and the radius is r.

The given equation is:

(x+5)^2+(y+7)^2=21^2

Another way to write this is:

(x-(-5))^2+(y-(-7))^2=21^2

Thus, we can see that h=-5 and k=-7.

The center is at (-5, -7).
