Answer:
Step-by-step explanation:
1/3 πr²h
Multiply bottom equation by -3 to add and eliminate y’s.
So...
5x-15y=10
+-9x+15y=18
You get -4x=28 so x=-7
Plug in to get y
5(-7)-15y=10
-35-15y=10
-15y=45
So y=-3
Check in other equation
3(-7)-5(-3)=
-21+15=-6
So x= -7 and y= -3

Step-by-step explanation:
Jace made 3 three pointers and 6 free throws.
3(3) + 6(1) = 15
Free throws = f
Three pointers = t
t(2) = f
t + f = 15
