Answer:
2x + 4y =8
substitute 0 for x
2 (0) + 4y = 8
0 +4y = 8
subtract 0 from both sides
-0 +4y =8 - 0
4y = 8
Divide both sides by 4
Y = 2

Answer:
56
Step-by-step explanation:
The probability both spiners land on red: 0,5*0,6=0,3 (0,5 is A spine lands on red and 0,6 is B spiner lands on red)
The number of both spiners land on red is 84.
So we have:
X——>100%
84——->30%
X=8400/30
X=280
The total number of all spines A and B for onse.
The probability to both spiners land on blue is:
0,5*0,4=0,2 (0,5 is probabiliti to A lands on blue, 0,4 is B lands on blue)
The number of both spiners land on blue is:
280*0,2=56
