simplified
Step-by-step explanation:
The answer to number 55 is B because if the cube has six numbers, then each number will have a probability of 1/6
1)4x-7=2x+9
Subtract 2x
2x-7= 9
Add 7
2x=16
X= 8
2(8)+9=25
(8,25)
X+y=10
-X-2y=-14
-y= -4
Y=4
X+4=10
X=6
(6,4)
(x,-4*x/2) or if you need the equation form x=x, y=-4+x/2
