Step-by-step explanation:
4÷12= 0.333333333333
12÷4=3
Since 4÷12 answer is different from the others, it's A. Let me know if this is correct! :)
17-4x = 1-4x+12-2x
17-4x = 13-6x | +4x
17 = 13-2x | -13
4 = -2x | :(-2)
-2 = x
We divide 60 by 2 as many times as possible to get 60 = 15 x 2 x 2. 2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2.
