5x^2 - 6x^2 = - x^2 so its either c or d.
and + 9x - )-3x) = 9x + 3x = + 12x
so the answer s C.
So first you add 40 percent and 30 percent to get 70 percent. After you do that subtract it from 100 to get 30. 30% times 30 is 9 so the answer is 9 cds.
22/400
Divide top and bottom by 2. 2 into 22 is 11 and 2 into 400 is 200.
11/200.
No other number can go into 11 and 200.
= 11/200 in Simplest form.
The answer is 680,000 because 4 is not greater than 5 so you replace it and the numbers behind it with 0s
