Hello :
<span> the equation of the circle is (x-a)²+(y-b)² = r²
A(a;b) center r : </span><span>radius
</span>in this exercice : (x+3)²+y²=25
Using a system of equations, it is found that Carol is 10 years old.
The complete problem is:
"Gerrys age is 5 more than three times Carols age. If the sum of their age is 45, how old is carol?"
<h3>System</h3>
The variables are:
Gerry is <u>5 more than three times Carol's age</u>, hence:
The sum of their ages is 45, hence:
We then use the first equation to find Carol's age:
Carol is 10 years old.
