I kind of forgot how to do it but here is what I know so far : first you separate the two parts into (5a^2 + 7a) + (6b^2-4b). This process is called grouping. Now you find the greatest common factor in both of them which later your equation will be a(5a + 7) +2b(3b - 2). That is all I can remember so hope that helped
.25+ .2 +.5= .95 so cousins cards make up 5% so 30 cards is half of that so that make 30 cards 2.5%. So 2.5 x 40 = 100% and 30 x 40=1200..... So Steve has 1200 baseball cards......
Hopefully I'm right... it just feels like it too much cards...;)
Since it's a six dice then it's out of x/6
How much is 4 to 6 ?
~3 (counting 4) 4.5.6...
So it's 3/6 = 1/2
