Treat this as an ordinary linear equation. Try to isolate x, as some value. Also remember the basic rules of inequalities: If you're dividing, or multiplying, by a negative, you flip the inequality.
No, not reasonable.
98.3 divides by 52.6
Brady used compatible numbers 100 divided by 5 =20
He should've used 100 divided by 50 = 2
Answer:
The constant speed with Ed is travelling is 60 mile per hour
Step-by-step explanation:
Given as :
The distance cover to travel from Jefferson to Holden is (D1) 250 miles
The distance cover to travel from Holden to Paxton is (D2) 50 miles
Total time taken to complete entire journey = T = 5 hours
Let The constant speed of Ed = S mph
Time = 
Or, Time = 
+ 
Or, 5 hour = 
+ 
Or, 5 × S = 250 + 50
So, 5 × S = 300
∴ S = 
I.e S = 60 mph
Hence , The constant speed with Ed is travelling is 60 mile per hour Answer
Given that the time taken to get to campus is inversely proportional to driving rate, let the time be t and rate be r, thus the function will be written as:'
t=k/r
where
k is the constant of proportionality given by:
k=tr
when r=20 mph, t=1.25 hrs
thus
k=20×1.25
k=25 miles
thus the formula is:
t=25/r
when r=55 mph, the value of t will be:
t=25/55
t=5/11 hours
Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.
