Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability blue or red marble: 7/10
Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability non-blue or red marble: 3/10

23. not equivalent because the first row 3x-9y=5 then if you multiplied this equation by 2 it will be 2(3x-9y) = 2(5) so 6x-18y= 10 not 6x-9y=10
24.equivalent because the second row 2y-6x=8 multiplied by 2 is 2(2y-6x)= 2(8) so 4y-12x=16
25. equivalent because the first row 5x+3y=19 multiplied by 2 is 2(5x+3y) = 2(19) SO 10X+6Y=38 and the second row 2x+4y=20 multiplied by 5 is 5(2x+4y)= 5(20) so 10x+20y=100
Answer:
B = 2
Step-by-step explanation:
( 2 b + 4 ) 2 − 12 = 0
Distribute..
2b+4(2)-12=0
combine like terms
2b+8-12=0
2b-4=0
Now solve this simple 2 step equation...
2b-4=0
+4=+4 <- add 4 to both sides
----------
2b=4
/2 = /2 <- divede both sides by 2
-----------
B = 2
61
26 + 35 = 61
