Explain why a step in solving the equation 4n= -36 is to divide both sides by 4. Then solve the equation
1 answer:
The correct value of ''n'' in this equation will be -9
- Step-by-step explanation:
In order to find the value of ''n'' in this equation of the first degree, just <u>isolate ''</u><u>n</u><u>''</u>, and divide the right side into the left side of the equation:
- Resolution:
So we can conclude that the value of ''n'' in this equation will be -9

Answer:
340 degrees
Step-by-step explanation:
So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).
So the circumference of a circle = 2pi(r)
This means:
6 = 2pi(r)
Which means that
r = 6/2pi or r = 3/pi
Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:
Arc length is defined by: length = θr
Where θ is our angle value.
So lets plug in:
Multiply by pi to get:
Divide by 3 to get that:
θ = 17pi/9
So if we convert that from radians to degrees we get 340 degrees.
