Let Ale’s money=a
Let Leo’s money=L
a=2L+3
You may have to rearrange any multiple choice answers algebraically, but they should all simplify down to the a= equation.
In problems like this, you can solve by thinking of how the word problem defines the variable. Ale is defined as twice Leo, plus three.
Answer: 1/8
Step-by-step explanation: 3/4 x 1/6 = 24/3 (simplify to 1/8)
The equation of circle is
(x-4)^2+(y-5)^2=R^2
if you replace the (13, -1) with x and y the R^2 will be 117
(x-4)^2+(y-5)^2=117
5x + 7x = 180 ⇒ properties of linear pair
12x = 80 ⇒ addition property (since (5 + 7)x = 12x)
x = 15 ⇒ Division property (since we divide both sides by 12)
