Answer is 5^12 which is choice A (assuming you meant to put the ^ symbol)
The bases are the same (both are 5), so you add the exponents: 4+8 = 12. The base stays the same the entire time.
So, 5^4*5^8 = 5^(4+8) = 5^12
First, we subtract 12x from both sides. We then get -4y=-12x+48. We then divide this by -4 on both sides to get the y by itself. We then get that the equation is y=3x-12.
That one looks very difficuly
1/50 converted to percent would be 2%. Here is how I got 2%. All I did was just divide 1 and 50 and got 0.2 then I had to multiply 0.2 * 100 and got 2%.
1/50 converted to decimal would be 0.02. I got 0.02 by dividing 1 and 50.
(3.25) or (2 4/6) should be your answer let mi kno if im right
