Answer:
3/30 =1/10
Step-by-step explanation:
add up the number of balls and then
number of black balls divided by the total number of balls.
(-6)-(+2)= -8
(-9)-(-8)= -17
(-6)-(+6)= -12
(-8)-(-8)= -16
(+5)-(+1)= 4
(+6)-(-2)= 8
(-3)-(+5)= -8
(-8)-(+5)= -13
(-9)-(-4)= -13
(+1)-(+3)= -2
(-3)-(+8)= -11
(+9)-(-4)= 13
(+8)-(-7)= 15
(-6)-(+3)= -9
(-3)-(+4)= -7
(-4)-(+3)= -7
(-6)-(+1)= -7
(+8)-(-8)= 16
(+1)-(+4)= -3
(+7)-(+9)= -2
(+5)-(-5)= 10
(+6)-(-9)= 15
(+7)-(-5)= 12
(+2)-(+1)= 1
(+2)-(+9)= -7
(+1)-(+1)= 0
(-2)-(+3)= -5
(+3)-(+4)= -1
(+8)-(-9)= 17
16 I guess
2*2 is 4
Then 4 times 4 is 16.
3x-6
y=4x-8 hope this helps:)
