Answer:
slope = 5/8
Step-by-step explanation:
use the slope formula to find the slope: 

if a = b and b = c, then a = c.
In this case if y = - 7 and -7 = z then y = z .................>(y = a, -7 = b and z = c)
Answer: B)
transitive property of equality
<span>let n+2=u
so, the equation became= [2/u]-[3/u]=5
=> [(2+3)/u]=5
=> 5/u=5
=> u=5/5=1
thus, u=1
we know u=n+2
so, n+2=1
=> n=1-2=-1
so, n=-1</span>
This would be 525 / 0.70 = $750 Answer
