Answer:
Solving the equation
for variable n we get ![\mathbf{n=5-2p}](https://tex.z-dn.net/?f=%5Cmathbf%7Bn%3D5-2p%7D)
Step-by-step explanation:
We need to solve the equation
for variable n
Solving:
![15 = 3n + 6p](https://tex.z-dn.net/?f=15%20%3D%203n%20%2B%206p)
Subtract both sides by 6p
![15-6p = 3n +6p -6p\\15-6p=3n](https://tex.z-dn.net/?f=15-6p%20%3D%203n%20%2B6p%20-6p%5C%5C15-6p%3D3n)
Switch sides of equality
![3n=15-6p](https://tex.z-dn.net/?f=3n%3D15-6p)
Divide both sides by 3
![\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p](https://tex.z-dn.net/?f=%5Cfrac%7B3n%7D%7B3%7D%20%3D%5Cfrac%7B15-6p%7D%7B3%7D%5C%5Cn%3D%5Cfrac%7B3%285-2p%29%7D%7B3%7D%5C%5Cn%3D5-2p)
So, solving the equation
for variable n we get ![\mathbf{n=5-2p}](https://tex.z-dn.net/?f=%5Cmathbf%7Bn%3D5-2p%7D)
Answer:
74km
Step-by-step explanation:
7 + 7 = 14
15 + 12 = 27
5 + 8 = 13
9 + 11 = 20
14 + 27 = 41
41 + 13 = 54
54 + 20 = 74
Answer:
3.
C. The domain is (1,+[infinity]) and the range is (-1,+[infinity])
4.
B. 6
5.
A. (-[infinity], 3)
Step-by-step explanation:
The Linear function has one independent and one dependent variable. The value of dependent variable can be found by taking the equation equals to 0. The domain function is set to analyse the range. The range can be set as -1 to 1. Any number between this is acceptable but outside this is not considered in the domain.
Usually the problem asks for you finding common multiples and common factors.
Usually these tools are used to solve a problem involving the first number.
Sometimes using common multiples and common factors are a waste of time but most of the time it just makes it easier to solve the problem.
