Answer:
<u><em>8,126,500</em></u>
Step-by-step explanation:
Use order of operations and deal with the multiplication first
(81265 * 169) - (81265 * 69)
13,733,785 - 5,607,285
<u><em>8,126,500</em></u>
D because you can just take the 0. off of 0.18!
It is not true for expressions with negative exponents
<u>Answer:</u>
$180
<u>Explanation:</u>
Alright, this took me a second of thinking.
So let's say our original price is x. Now to get to the discounted price of 135, we had to take off 25%. Because we know 25% of x is now gone, 135 must be 75% of x. So in this case we would divide 135 by .75 and that would give us 180.
Now to check this out, we just have to remove that 25% and see if we still get 135. So when we multiply 180 x .25 we get 45. Then subtracting our 45 from 180 we get 135, proving that the original price is indeed $180.
