Hello!
To find your answer you must subtract first:
70 - 21 = 49
Now, how much percent is 49 of 70?
49/70 = 0.7000
0.7000 * 100 = 70.00%
49 is 70% of 70.
I really hope this helped you! :)
To check your answer: (70 × 70.00)/100 = 49
If you would like to factor completely 13m^2n^3p + 21mp^2, you can do this using the following steps:
<span>13m^2n^3p + 21mp^2 = mp * (13mn^3 + 21p)
</span>
The correct result would be mp * (13mn^3 + 21p<span>).</span>

Since we know that all angles in a triangle add up to
, we can solve for
and substitute it back into
to find
.
![\begin{aligned}m\angle N+m\angle O+m\angle P&=180\\(5x-8)+(x-5)+(6x+1)&=180\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7Dm%5Cangle%20N%2Bm%5Cangle%20O%2Bm%5Cangle%20P%26%3D180%5C%5C%285x-8%29%2B%28x-5%29%2B%286x%2B1%29%26%3D180%5Cend%7Baligned%7D)
Remove the parentheses and combine like terms.
![\begin{aligned}5x-8+x-5+6x+1&=180\\(5x+x+6x)+(-8-5+1)&=180\\12x-12&=180\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D5x-8%2Bx-5%2B6x%2B1%26%3D180%5C%5C%285x%2Bx%2B6x%29%2B%28-8-5%2B1%29%26%3D180%5C%5C12x-12%26%3D180%5Cend%7Baligned%7D)
Add
to both sides of the equation.
![\begin{aligned}12x-12&=180\\12x&=192\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D12x-12%26%3D180%5C%5C12x%26%3D192%5Cend%7Baligned%7D)
Divide both sides of the equation by
.
![\begin{aligned}x=16\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7Dx%3D16%5Cend%7Baligned%7D)
Now that we have the value of
, we can substitute it back into
to find
.
![\begin{aligned}m\angle O&=(x-5)\\&=16-5\\&=\boxed{11}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7Dm%5Cangle%20O%26%3D%28x-5%29%5C%5C%26%3D16-5%5C%5C%26%3D%5Cboxed%7B11%7D%5Cend%7Baligned%7D)
Answer: Multiply
2 * 1 5/6
Convert 1 5/6 into an improper fraction:
2 * 11/5
Multiply:
22/5
Convert to mixed number:
4 2/5
So 22/5 or 4 2/5 of a pan of brownies was left.
