Answer:
(s+16)(s-16)
Step-by-step explanation:
s^2-256
s^2-(16)^2
<u>a^2-b^2= (a+b)(a-b)</u>
<u />
(s+16)(s-16)
you need to find to find the value of x and y.
2x>(-15-5y)
x>(-15-5y)/2
now put this in to other equation and solve for y and then put the y value in and find x.
Answer:
65 mph
Step-by-step explanation:
To find the unit rate (miles per hour), we can use the equation
![r=\frac{d}{t}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%7D%7Bt%7D)
Where
r=rate (miles per hour)
d=distance (in miles)
t=time (in hours)
Using the given information, we can plug in
![d=97\frac{1}{2}](https://tex.z-dn.net/?f=d%3D97%5Cfrac%7B1%7D%7B2%7D)
![t=\frac{3}{2}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B3%7D%7B2%7D)
So, our equation is
![r=\frac{97.5}{1.5}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B97.5%7D%7B1.5%7D)
When we divide 97.5 and 1.5, we get
![65](https://tex.z-dn.net/?f=65)
So,
![r=65](https://tex.z-dn.net/?f=r%3D65)
In conclusion, the rate (miles per hour) is 65 mph.
So,
187 divided by 7
187/7
Mixed: 26 5/7
Decimal: 26.714285 (there is a vinculum over the "714285")
