a( 10 ) - b( 5 ) = 5 ?
a and b both have the probability of 3/4
Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators

1 is the answer. -(-4)- 3 = 4-3 = 1 .
A:B = 3:4 = 9:12 B:C = 6:5 = 12:10 So A:B:C = 9:12:10

first you add 2 to the 8. the 2 crosses out itself so now you have b over 4 equals 10. then you multiply the 4 to the ten and the 4 the 4 crosses out itself and you end up with b= 40

you take the y=mx+b alright then you plug in your numbers. So say you got (5,4)(X,Y) and the slope was 2 the equation would then be 4=2(5)+b. Then you do 2x5 which equals 10. Then you divide the 10 on both sides. the 10 and the 10 cancel each other out and the 4/10 =2/5 and then 2/5=b. There you have it!

a = 11 and b = 5.
