Answer:
See below (I hope this helps!)
Step-by-step explanation:
When dividing exponents of the same base, we can simply subtract the powers so the new power would be 6 / 7 - 2 / 7 = 4 / 7, hence we need to write
as a radical. When writing fractional exponents as radicals, the denominator of the fractional exponent is the index of the radical and the numerator is the exponent of the base inside the radical, hence, our answer is
.
Answer:
<h2>-34</h2><h2 />
Step-by-step explanation:
4x - 5y x=4 , y=10
= (4*4) - (5*10)

To find the sale price now you can divide x by 5 and then multiply that by 4
Answer:
![Z=\frac{W}{2(X+Y)}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7BW%7D%7B2%28X%2BY%29%7D)
Step-by-step explanation:
W = 2ZX + 2ZY
