Step-by-step explanation:
n+1/2n=7/2
2n^2+1/2=7/2
4n^2+2=14
4n^2=12
n^2=3
n=radical3
Answer:
960 km
Step-by-step explanation:
Speed = Distance/Time.
From the question, we are to find the Distance.
The formula for Distance is given as:
Speed × Time.
From the question:
Speed = 960 km/hr
Time = 1 hour
Distance = 960 km/hr × 1 hour
Distance = 960 km
Therefore, the airplane can travel for 960km in 1 hour
Public schools are free to use for the public (despite uniform and others), and jobs involved in public schools (like teachers) get their money from the government as everything funded towards public schools are by the government
Answer:
Solutions are;
x = -8
x = -3.2
Step-by-step explanation:
Here, we want to solve the given equation for x
|(x-4)/(x + 5)| = 4
From what we have, this is an absolute value equation and thus, we are going to have two solutions
These are;
x-4/x+ 5 = 4
x-4 = 4(x + 5)
x-4 = 4x + 20
x-4x = 20 + 4
-3x = 24
x = -24/3
x = -8
secondly;
x-4/x+5 = -4
x-4 = -4(x + 5)
x-4 = -4x - 20
x + 4x = -20 + 4
5x = -16
x = -16/5
x = -3.2
