5/2 ^2 = 6 1/4 = 6.25
3/4^3 = 27/64 = 0.4201875
6 1/4 + 27/64 = 6 43/64 (mixed number)
6.25 +0.421875 = 6.671875 (decimal)
not sure what format you need, since the question was in fraction form, I think you need to answer using a mixed number though.
Answer:x=4,8
Step-by-step explanation:
Given
![x=2\sqrt{x-4}+4](https://tex.z-dn.net/?f=x%3D2%5Csqrt%7Bx-4%7D%2B4)
![x-4=2\sqrt{x-4}](https://tex.z-dn.net/?f=x-4%3D2%5Csqrt%7Bx-4%7D)
Squaring both sides
![(x-4)^2=4(x-4)](https://tex.z-dn.net/?f=%28x-4%29%5E2%3D4%28x-4%29)
![x^2+16-8x=4x-16](https://tex.z-dn.net/?f=x%5E2%2B16-8x%3D4x-16)
![x^2-12x+32=0](https://tex.z-dn.net/?f=x%5E2-12x%2B32%3D0)
![x=\frac{12\pm \sqrt{12^2-4\times 32}}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B12%5Cpm%20%5Csqrt%7B12%5E2-4%5Ctimes%2032%7D%7D%7B2%7D)
![x=\frac{12\pm 4}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B12%5Cpm%204%7D%7B2%7D)
![x=4,8](https://tex.z-dn.net/?f=x%3D4%2C8)
Simplified form of 1/56 divided by -30 is ![=-\frac{1}{1680}](https://tex.z-dn.net/?f=%3D-%5Cfrac%7B1%7D%7B1680%7D)
Step-by-step explanation:
We need to solve 1/56 divided by -30 in simplest form.
Solving:
Writing in mathematical form:
![\frac{1}{56}\div -30](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B56%7D%5Cdiv%20-30)
Converting division symbol into multiplication and taking reciprocal of -30
![=\frac{1}{56}\times \frac{1}{-30}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B56%7D%5Ctimes%20%5Cfrac%7B1%7D%7B-30%7D)
Simplifying:
![=\frac{1}{56*-30}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B56%2A-30%7D)
![=-\frac{1}{1680}](https://tex.z-dn.net/?f=%3D-%5Cfrac%7B1%7D%7B1680%7D)
So, simplified form of 1/56 divided by -30 is ![=-\frac{1}{1680}](https://tex.z-dn.net/?f=%3D-%5Cfrac%7B1%7D%7B1680%7D)

You can find the answer for any conversion questions like this
write the values first.
47.85ft - x
3.3ft- 1m
Then cross multiply..
47.85=3.3x
then do opposite operation the variable side
and divide.
47.85÷3.3=14.5m
x= -4 because 1.4 times -4=- 5.6 and 2.6 times -4=-10.4 and when we add to numbers postive or negative numbers it stays positive or negative depnding on the problem and 10.4 + 5.6 + 16 however becuase both were negative the answers stays negative making the answer _ 16 and it says 1.4x+2.6x=-16 so the correct answer is x= -4
